Hieff™ Taq DNA polymerase is a thermostable recombinant wild type DNA polymerase expressed by Thermus aquaticus with a molecular weight of 94 KDa. It has 5'→3' polymerase activity and 5'→3' exonuclease activity but without 3'→5' exonuclease activity. The amplified product has 3'- dA and can be directly used for TA cloning.

Features

  • 5'→3' DNA polymerase activity
  • 5'→3' exonuclease activity
  • Hieff™ Taq DNA polymerase is an ideal tool for standard PCR with templates of 5 kb or less

Applications

Genotyping, colony PCR and other conventional PCR

Specifications

Polymerase Taq DNA polymerase
Molecular Weight 94 KDa
Unit Definition Using the activated DNA of salmon sperm as template/primer, the activity is defined as one active unit (U) when 10 nmol of total nucleotide was ingested as acid insoluble substance at 74℃ for 30 min.

Glycerol Content

Contains Glycerol

Storage

The product should be stored at -25℃~-15℃ for two years.

Store this enzyme at -20°C and avoid repeated freeze-thaw cycles to preserve catalytic activity. The product is shipped Dry Ice and remains stable for up to one year from the date of manufacture when stored under recommended conditions. Aliquoting the stock solution into single-use volumes is recommended for enzymes used infrequently to minimize thermal cycling of the bulk stock.

Genotyping, colony PCR and other conventional PCR. Always verify compatibility with your specific template, buffer, and downstream workflow.

One unit (U) is defined as the amount of enzyme required to catalyze the incorporation of 10 nmol of deoxyribonucleotide into acid-insoluble material in 30 min at 74°C using activated salmon sperm DNA as template/primer.

This enzyme is produced as Recombinant (E. coli) and supplied as a Research Use Only (RUO) reagent. Each lot is subjected to activity assay, purity assessment by SDS-PAGE, and functional validation prior to release. A Certificate of Analysis (CoA) and Safety Data Sheet (SDS) are available on request.

Standard Taq DNA polymerase lacks 3′→5′ proofreading exonuclease activity, resulting in an error rate of approximately 1 in 10⁵ bp per cycle. It produces predominantly A-tailed PCR products, compatible with TA cloning. Typical routine amplification yields fragments up to ~5 kb from genomic DNA and up to ~10 kb from plasmid/cDNA templates under optimized conditions.
