Taq DNA Polymerase, concentrated

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 in PCR. In some cases, such as RAPD PCR, adding large volume of general Taq DNA polymerase (5 U/μl), which has a high concentration of glycerol in its storage buffer, will increase the glycerol concentration in the reaction mix, interfering with PCR performance. The use of concentrated Taq DNA Polymerase (25 U/μl ), with a far slimmer dose of glycerol, can prevent poor PCR efficiency. Note: Concentrated Taq DNA Polymerase (GenScript, E00012) is supplied with 10X reaction buffer containing 15 mM magnesium chloride. The dNTP (10 mM) mix may be ordered separately.

产品简介
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 in PCR*. In some cases, such as RAPD PCR, adding large volume of general Taq DNA polymerase (5 U/µl), which has a high concentration of glycerol in its storage buffer, will increase the glycerol concentration in the reaction mix, interfering with PCR performance. The use of concentrated Taq DNA Polymerase (25 U/µL ), with a far slimmer dose of glycerol, can prevent poor PCR efficiency.
Key Features Terminal Transferase Activity: A single nucleotide (adenosine) is added to the 3’ end of the extension product.
High-Purity: No contamination activity has been detected in standard test reactions.
Unit Definition One unit is defined as the amount of enzyme that can incorporate 10 nmol of dNTP into acid-insoluble material in 30 minutes at 74°C.
Concentration Supplied in 25 units/µL in 20 mM Tris HCl (pH 8.0), 0.1 mM EDTA, 1 mM DTT, 0.1% Triton X-100 and 50% glycerol.
Formulation Genscript Taq DNA Polymerase has been formulated using GenScript’s proprietary technology. The enzyme can be shipped at room temperature or stored at 37°C for seven days without any significant loss of activity.
Reaction Buffer 10 X reaction Buffer (with Mg2+): 500 mM KCl, 100 mM Tris HCl (pH 9.0 at 25℃), 15 mM MgCl2, 1% Triton X-100 Buffer. This buffer is optimized for use with 200 µM dNTPs.
Important: If another reaction buffers are used with Taq DNA Polymerase, Triton X-100 must be added to a final concentration of 0.1% to ensure high enzyme activity with Taq DNA Polymerase.
Application The applications of Taq DNA Polymerase are as follows:
● PCR*
● 3' A-tailing of blunt ends (T/A-cloning)
● Primer extension
● DNA labeling reactions
The PCR process is covered by US. Patents Nos. 4683195 and 4683202, issued to Cetus and owned by Hoffman-La Roche Inc. GenScript does not encourage or support the unauthorized use of the PCR process. Use of this product is recommended for persons who either have a license to perform PCR or are not required to obtain a license. Sale of this product is restricted to regions or countries where native Taq DNA polymerase patents have been invalidated.
Storage & Stability Store the product at -20°C
Note Concentrated Taq DNA Polymerase (GenScript, E00012) is supplied with 10X reaction buffer containing 15 mM magnesium chloride. The dNTP (10 mM) mixture may be ordered separately (See related products).
