FAQ

This can be due to the following situations:
a) Inadequate annealing temperature/ primer concentration. The reaction mix composition may affect the melting properties of primers and DNA. Adjust the annealing temperature to accommodate the primer with the lowest melting temperature (3 ° to 5 °C lower than T_m). Optimise annealing temperature using temperature gradient PCR. Increase primer concentration for lower yield amplicons.
b) Inadequate cycling conditions. Increase extension time and/or number of cycles.
c) Presence of PCR inhibitors. Some DNA isolation procedures, particularly genomic DNA isolation, can result in the co-purification of PCR inhibitors. Reduce the volume of template DNA in reaction or dilute template DNA prior to adding to the reaction. Diluting samples even 1:10,000 has been shown to be effective in improving results, depending on initial DNA concentration.
d) Inadequate amount of template DNA. Titrate template amount. We recommend starting with 20-50 ng of genomic DNA.
c) Concentration of magnesium is too low. Mg²⁺ is included in the Master Mix at a final concentration of 2.5 mM, which is sufficient for most targets. For some targets, higher Mg²⁺ concentration may be required. Titrate from 2.5 mM to 4 mM (final concentration) in 0.25 mM increments. (Note: MgCl₂ is not provided in separate tubes).

Adjust annealing conditions and/or design another pool of primers, avoiding complementary sequences. Ensure that each primer pair originates a single product without primer-dimers in individual PCR reactions. If necessary, reduce primer concentration. Reduce the number of cycles.

Multiplex PCR NZYTaq 2x Colourless Master Mix allows efficient multiplexing of targets ranging in size from 70 bp to 2.5 k.

Such type of probes have the purpose of increasing the melting temperature of the probe which can be beneficial for some assays. We offer two types of probes for customers who need such type of characteristic - MGB probes and Xs probes. These probes differ in the type of chemistry used to achieve the higher Tm.

For best results, store oligos in a TE buffer. If chelating/buffering agents aren't suitable, opt for Low-TE buffer or sterile water.

Recommended storage order: TE > Low-TE > lyophilized/dried > water.

Ideal storage temperature is -30 °C to -15 °C. Refrigerated oligos (2 °C to 8 °C) remain stable for at least one year. Oligos stored at room temperature (dried or dissolved in TE/ Low-TE buffer are stable for at least one month. 

Protect from UV light, especially for fluorophore-modified oligos, as they may bleach. Treat modified oligos like non-modified ones for optimal storage.

Yes, desalting is a standard purification procedure for all our standard oligos. 

In the post-synthesis phase, during the activation of oligonucleotides for biological applications, the formation of salts occurs. Notably, these salts may serve as inhibitors, particularly in the context of polymerase chain reaction (PCR) assays.

Please be aware that specific applications, such as cloning, may necessitate or strongly benefit from additional purification. 

NZYtech ships oligonucleotides in TE (Tris-EDTA) buffer as the default because it has proven to be the most stable method for storing oligos. TE buffer ensures the integrity of the DNA during transportation, preventing degradation. However, we understand that preferences may vary. If you have specific storage or shipment conditions in mind, you can choose from other standard conditions available to meet your requirements. Our goal is to provide flexibility while maintaining the high quality of our products.

By default, oligos will be shipped at a concentration of 100 µM (100 pmol/µl)

However, if the yield of an oligo intended for delivery in a 2 ml tube exceeds 180 nmol, we take a specialized approach. In such cases, we ship it at a concentration of 1 nM (1 nmol/µl). This measure is implemented to ensure the best handling and stability of your oligonucleotide order during transit.

NZYtech provides multiple purification options tailored to diverse needs:

Desalting: Desalting is a standard purification procedure for all our standard oligos. 

In the post-synthesis phase, during the activation of oligonucleotides for biological applications, the formation of salts occurs. Notably, these salts may serve as inhibitors, particularly in the context of polymerase chain reaction (PCR) assays.

Cartridge: A step beyond desalting, cartridge purification eliminates failure sequences, enhancing the purity of the final oligo mixture.

HPLC (High-Performance Liquid Chromatography): Ideal for achieving higher purity, HPLC removes truncated sequences and synthesis-related salts. Some modifications often require HPLC purification due to lower coupling efficiency. For certain products like dual-labelled qPCR probes, the HPLC purification step is automatically included in the price calculation as a standard feature.

PAGE (PolyAcrylamide Gel Electrophoresis): Designed to minimize impurities and ensure the highest percentage of full-length oligos. While it significantly lowers yield, PAGE purification is recommended for oligos intended for demanding applications such as mutagenesis and cloning.

NZYtech introduces a dedicated product class for these oligonucleotides, defaulting to HPLC purification and quality assessment via UPLC-MS to ensure adherence to stringent quality standards. These dual-labelled oligos are available for order under the following categories:

TDP (Twice Dyed Probes): Hydrolysis probes, serving as the equivalent of Taqman probes in qPCR.

XS probes (MGB alternative): Hydrolysis probes equivalent to MGB probes, designed to elevate the Tm for enhanced specificity. 

MB probe (Molecular Beacon Probes): Featuring stem-loop structures. 

FRET probe (Fluorescent Resonance Energy Transfer probes): Tailored for applications like real-time PCR. 

A: While we guarantee a minimum yield for non-labeled, non-HPLC/PAGE purified standard DNA oligos up to 30 bases, it's common for customers to receive yields surpassing this minimum guarantee:

The yield of an oligo depends on its sequence. Some sequences, like those with multiple consecutive dG's, may yield less, but in most cases, yields are higher.

For qPCR TDP probes, the approximate yield is:

This can be due to the following situations:

a) Inadequate annealing temperature. The reaction mix composition may affect the melting properties of primers and DNA. Adjust the annealing temperature to accommodate the primer with the lowest melting temperature (5 ° to 10 °C lower than Tm).
b) Presence of PCR inhibitors. Some DNA isolation procedures, particularly genomic DNA isolation, can result in the co-purification of PCR inhibitors. Reduce the volume of template DNA in reaction or dilute template DNA prior to adding to the reaction. Diluting samples even 1:10,000 has been shown to be effective in improving results, depending on initial DNA concentration.

The master mix should be stored at -20 ºC, in a constant temperature freezer. Minimize the number of freeze-thaw cycles by storing in working aliquots. The Mix maybe stored at 4 °C for up to 7 days.

Speedy NZYProof DNA polymerase has 3´→ 5´ exonuclease activity and will generate blunt-ended products. So, blunt-end cloning is recommended, by using NZY-blunt PCR cloning kit (MB121) or other similar cloning kit. Nevertheless, if TA cloning is required, the generated blunt-ended PCR fragments can be modified by adding 3´A-overhangs with a different polymerase, such as Taq DNA polymerase (see the A-tailing protocol in the product brochure of NZY-A PCR cloning kit – MB053). Due to the strong proofreading activity of Speedy NZYProof DNA polymerase, we recommend immediately proceed with cloning after this procedure, in order to avoid lost of the 3´A-overhangs during storage. Alternatively, the PCR products can be cloned using the innovative NZYEasy Cloning & Expression Systems in a rapid, precisely and ligase-independent manner. For optimal cloning efficiencies, silica-column purification of the PCR product using NZYGelpure kit (MB011) or other similar kit is highly recommended. This procedure will remove dNTPs, unused primers and other impurities. Spin-column purification is sufficient as long as the product is >90% pure. Gel-extraction should be performed in case non-specific amplifications and/or primer-dimers are formed.

NZYEasy Cloning & Expression System relies on a simple reaction that enables the assembly of DNA inserts into a cloning or an expression vector in a precise and predetermined order. No insert phosphorylation, blunt-end polishing or digestion is required, thus making the NZYEasy Cloning & Expression System fast when compared to classical cut and ligation methods. Furthermore, cloning can be achieved either directly using blunt-ended or Taq-generated PCR products. The cloning is performed in a single reaction with high efficiencies compared to traditional methods, even when simultaneously clone multiple inserts into one vector.

Spin-column purification of PCR products is highly recommended to remove dNTPs and impurities resulting from the amplification. Presence of non-specific amplification products and/or primer-dimers requires gel-purification of the amplified nucleic acid, which will enhance cloning efficiencies.

No, you can use standard, desalted primers.

Yes. Inserts correctly cloned into pHTP1 expression vector will maintain reading frames starting on the ATG codon.

We recommend using E. coli DH5α (NZYTech, cat. No. MB004) as a host for cloning. Regarding expression, all E. coli strains expressing the gene that codifies for T7 RNA polymerase, such as BL21(DE3) (NZYTech, cat. No. MB006), are suitable to use.

Yes, the NZYEasy Cloning & Expression System allows multiple fragment cloning into one pHTP vector. DNA fragments will be correctly annealed together in the desired order on the pHTP vector through the action of the highly efficient NZYEasy enzyme mix, free of any DNA ligase. Just combine the PCR-generated fragments with appropriate complementary overhangs, by allowing assembling in the order you choose, and a linearized pHTP vector. Both first and last inserts should have overhangs complementary with respective ends of the vector, thereby allowing efficient cloning. Each DNA fragment, encoding for an individual domain of the final multidomain construct, are kept in frame and are separated from each other by a linker sequence of 6 amino acids.

The number of inserts that can be joined in the same vector depends on their length and sequence. NZYEasy Cloning & Expression System has been tested efficiently for cloning 5 different genes of around 500-700 bp in size in the same vector. Note that the cloning efficiency decreases as the size of the final construct increases. However, if the simultaneous cloning of the desired inserts does not work, you can try a sequential cloning approach.

Gel-purify the PCR band of interest in order to remove the template plasmid. Alternatively, digest PCR products with DpnI (NZYTech cat No. MB078) restriction enzyme to eliminate parental methylated DNA templates. When possible, you can also reduce the amount of template plasmid DNA to 0.1-0.5 ng per 50 µL PCR reaction.

Perform a cloning reaction using the PCR fragment provided as positive control with NZYEasy Cloning & Expression kits. Using this procedure, you can evaluate the functionality of cloning and transformation conditions.
If cloning and transformation result successfully using the positive control, then make sure that your DNA insert and the linearized pHTP vector share the required end-terminal complementarity by analysing primer sequences; verify the quality of the insert by gel electrophoresis; optimize the ligase-independent cloning reaction trying different vector:insert molar ratio, and/or repeat PCR and gel-purify the PCR product for a new cloning reaction and transformation. Alternatively, consider that the cloned insert may be toxic to E. coli. If this is the case, and if you are directly cloning into the expression vector, try to clone first into the low-copy number pHTP0 vector.
If cloning and transformation do not result successfully, check also the transformation efficiency of E. coli competent cells; verify if LB plates contain the appropriate antibiotic for the pHTP vector you are using; make sure you correctly handle the NZYEasy enzyme mix; verify if a specific component is missing in the cloning reaction.

No, Gene Fragments quality control procedure only involves size verification by electrophoresis. NZYtech’s Gene Fragments are synthesized under the same careful conditions as our custom gene synthesis service. However, since Gene Fragments are delivered to you as uncloned products the existence of minor populations of mutated or truncated fragments is inevitable. 

 Gene fragments are delivered as uncloned products.

NZYtech standardly delivers ≥400 ng dry dsDNA fragments. Please note that due to inherent losses during the freeze-drying process post-aliquoting, the final yield may vary slightly. To compensate for this and ensure sufficient plasmid quantity, a slightly higher amount than specified is typically provided. We recommend resuspending the sample upon receipt and performing a new concentration measurement prior to use.

For higher accuracy and specificity, fluorescence-based quantification of dsDNA is available upon request (additional charges apply). In this case, the dsDNA is delivered in liquid form, resuspended in water.
