Taq DNA Polymerase (1 U/μl), dNTPack

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

1 kit containing 5 components

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
