Taq DNA Polymerase without Mg²⁺

Key Features

Terminal transferase activity: Taq DNA Polymerase has terminal transferase activity, which results in the addition of a single nucleotide (adenosine) at the 3' end of the extension product.
High purity: No contamination activity has been detected in standard test reactions.

Description

Taq DNA Polymerase is a thermostable DNA polymerase isolated from an E. coli strain that carries the Taq DNA polymerase gene. Taq DNA polymerase is the most common polymerase used for PCR^*.

Applications

The applications of Taq DNA Polymerase include the following:

PCR^*
3' A-tailing of blunt ends
Primer extension
DNA sequencing

Formulation

GenScript Taq DNA Polymerase has been formulated using GenScript's proprietary technology. The enzyme can be shipped at room temperature or even 37�C for seven days without any loss of activity.

Unit Definition

One unit is the amount of enzyme that can incorporate 10 nmol of dNTP into acid-insoluble material in 30 minutes at 74�C.

10 X Reaction Buffer (without Mg²⁺)

500 mM KCl, 100 mM Tris HCl (pH 9.0 at 25�C), 1% Triton X-100 Buffer. This buffer is optimized for use with 200 �M dNTPs.
Note: If the reaction is performed without this buffer, then add 0.1% Triton X-100 (final concentration) to ensure high activity.

Storage Buffer and Concentration

Taq is delivered in 5 units/�l in 20 mM Tris HCl (pH 8.0), 0.1 mM EDTA, 1 mM DTT, 0.1% Triton X-100 and 50% glycerol.

Storage:

-20�C
