DNA polymerase

The Uses of DNA polymerase

Taq DNA Polymerase from Thermus aquaticus has been used in the process of DNA extraction (during gene amplification and sequencing). It has been used in genotyping. It has also been used in polymerase chain reaction (PCR) to study the constitutive production of epithelial neutrophil activating peptide 78 (ENA-78) and interleukin-8 (IL-8).

The Uses of DNA polymerase

REDTaq^? Genomic DNA Polymerase has been used as a component of the polymerase chain reaction (PCR) mix for PCR amplification. It has also been used as a component of the preamplification mix for PCR in amplified fragment length polymorphism (AFLP) analysis of Fusarium oxysporum sp. isolates.

The Uses of DNA polymerase

For routine PCR amplifications REDTaq^? DNA Polymerase has been used in polymerase chain reaction (PCR) and reverse transcription-polymerase chain reaction (RT-PCR) analysis.

General Description

Klenow enzyme is the large, C-terminal fragment (M_r 76,000) of E.coli DNA polymerase I, which can be obtained by subtilisin treatment of intact DNA polymerase I. It retains the 5′→3′ polymerase and the 3′→5′ exonuclease activities of intact DNA polymerase I, but lacks the 5′→3′ exonuclease activity of the native enzyme. The enzyme catalyzes the addition of mononucleotides from deoxynucleoside-5′-triphosphates to the 3′-hydroxyl terminus of a primer/template DNA. This property is used to synthesize DNA complementary to single-stranded DNA templates.
Klenow Enzyme is formed by subtilisin treatment of DNA polymerase I.

Biochem/physiol Actions

Taq polymerase catalyzes oligonucleotide primer-driven, DNA template dependent incorporation of dNTPs into complimentary DNA strands. It displays both 5′ to 3′ polymerase and exonuclease activities.
