描述

一般說明

Klenow Fragment is a mesophilic DNA polymerase derived from the E.coli Polymerase I DNA-dependent repair enzyme. The enzyme exhibits DNA synthesis and proofreading (3′ → 5′) nuclease activities, and, in the absence of the holoenzyme′s (5′→3′) nuclease domain, displays a moderate strand displacement activity during DNA synthesis. The protein is expressed as a truncated product of the E.coli PolA gene.

應用

Suitable for:

• DNA blunting by fill-in of 5′ overhang
• Second strand cDNA synthesis
• Sequencing
• Site-specific mutagenesis

特點和優勢

• Ultra-purification process for ultimate enzyme performance
• Highest quality specifications for ultimate product consistency
• Undetectable DNA and nuclease contamination
