HCY™ Taq DNA Polymerase Kit

Cat. No.: E0060K101

Taq DNA Polymerase Jane is one of the most commonly used DNA polymerases.


HCY™ Taq DNA Polymerase Kit

HCY™ Taq DNA Polymerase is derived from Thermus aquaticus and has been modified by mutation and recombination to have higher thermal stability and amplification efficiency than wild-type Taq DNA polymerase. The molecular weight of HCY™ Taq DNA Polymerase is 106 KD. HCY™ Taq DNA Polymerase has 5′-3′ DNA polymerase activity and 5′-3′ exonuclease activity, and no 3′-5′ exonuclease activity. ‘ exonuclease activity. In PCR reaction, HCY™ Taq DNA Polymerase extends as fast as 5 kb/min, and the product carries an A base at the 3’ end, which can be directly cloned with TA vector.


HCY™ Taq DNA Polymerase is Recombinant Taq DNA Polymerases, which is genetically modified by mutation and recombination and purified by expression in E. coli.


  • Amplification of DNA by PCR.
  • HCY™ Taq enzyme can amplify DNA fragments up to 5 kb in length. It is usually suitable for amplifying DNA fragments up to 3 kb in length.
    Most PCR products amplified with this product have an “A” base at the 3′ end and can therefore be cloned directly into the T-Vector. They can also be cloned into smooth end vectors after end smoothing and phosphorylation.

Activation Definition

Using activated salmon sperm DNA as a template/primer, the activity of 10 nmol of whole nucleotides ingested as acid-insoluble material at 74°C for 30 minutes is defined as one activity unit (U).

Performance of HCY™ Taq DNA Polymerase

Taq DNA Polymerase

HCY™ Taq DNA Polymeras Amplified Fragment Lengths

  • HCY™ Taq DNA Polymeras can amplify 0.5kb/1kb/2kb/5kb fragments of different lengths of λDNA (0-5 kb) with high efficiency.
  • M indicates DL10,00 DNA Marker.

Taq DNA Polymerase

HCY™ Taq DNA Polymeras Amplification Sensitivity

  • Amplification of E. coli 300bp fragment with the addition of 0pg/10pg /100pg/1ng/10ng/100ng concentration templates; it can be seen that this product can amplify E. coli genes as low as 1ng template amount.
  • NC indicates negative control for HCY™ Taq DNA Polymerase amplification without template.
  • M indicates DL500 DNA Marker.

HCY™Taq DNA Polymeras Amplification Speed

  • The extension time was 30 sec./60 sec./120 sec. for amplification of 0.5kb/1kb/2kb/5kb size target fragments;
  • It can be seen that the extension time of 30 sec. and 60 sec. can well amplify 2kb and 5kb DNA fragments, respectively, indicating that the PCR reaction system with λ DNA as template can set the extension time according to 5kb/min.
  • M is for DL10,000 DNA Marker.

Quality Control

  • SDS-PAGE electrophoretic purity greater than 98%;
  • Functional test: sensitivity, specificity, reproducibility of PCR;
  • No exogenous nuclease activity, no exogenous endonuclease, and exonuclease contamination;
  • No expression of host nucleic acid residue.
