General description

Taq DNA Polymerase (1 U/μl), dNTPack, comprises Taq DNA Polymerase and a ready-to-use solution of PCR grade nucleotides. Taq DNA polymerase is a highly processive 5′-3′ DNA polymerase that lacks 3′–5′ exonuclease activity. It is stable during prolonged incubations at elevated temperatures (+95 °C). Additionally, it exhibits highest activity at a pH of around 9 (adjusted at 20 °C) and temperatures around +75 °C. It accepts dNTP analogs as substrates. There is no difference in stability or performance when compared to the standard concentration of Taq DNA Polymerase.


Taq DNA Polymerase (1 U/μl), dNTPack may be used for:
  • PCR
  • RT-PCR
  • Other primer-extension reactions, such as sequencing and labeling

Unit Definition

One unit Taq DNA Polymerase is defined as the amount of enzyme that incorporates 10 nmol of total deoxyribonucleosidetriphosphates into acid precipitable DNA within 30 minutes at +75 °C under the assay conditions stated under unit assay.

Unit Assay: Incubation buffer:
67 mM Tris/HCl; pH 8.3/25 °C, 5 mM MgCl2, 10 mM Mercaptoethanol, 0.2% Polydocanol, 0.2 mg/ml Gelatine, 0.2 mM each dATP, dGTP, dTTP and 0.1 mM dCTP.

Incubation procedure:
M13mp9ss, M13 primer (17mer) and 1 μCi (α-32P) dCTP are incubated with suitable dilutions of Taq DNA Polymerase in 50 μl incubation buffer at +65 °C for 60 minutes. The amount of incorporated dNTPs is determined by trichloroacetic acid precipitation.

Volume Activity: 1 U/μl
