This is an N-terminal truncation of the E. coli DNA Polymerase I protein, at amino acid #323. This truncation results in the deletion of the 5' to 3' exonuclease domain, but leaves the polymerase function unaffected. The introduction of two additional mutations (D355A and E357A) results in the abolition of the 3' to 5' exonuclease activity.Available in three concentrations and supplied with 10X reaction buffer. The highest-concentration (200 U/µl) enzyme is also supplied with 1X dilution buffer.
Protein Uses:
Didexoy sequncing.
Fill-in of restriction fragments to create blunt ends.
Second strand cDNA synthesis for labeling and for use in mutagenesis protocols.
Labeling of DNA with nucleotide analogs (e.g. for use as microarray probes).
Dye incorporation assays.
Probe labeling.
Additional Information:
Single recombinant protein, not a fusion construct, expressed in E. coli.
High purity, low DNA content.
Specific activity: 15,000 - 20,000 U/mg.
Has strand displacement capability.
No intrinsic exonuclease activity.
Error rate of 1/10000 bases.
