Anti-E.coli DNA polymerase 1 antibody, rabbit serum

Description

E.coli DNA polymerase 1 (928 aa; 103 kDa) is encoded by polA gene and involved in DNA replication and repair. In addition to polymerase activity, this DNA polymerase exhibits 3′ to 5′ and 5′ to 3′ exonuclease activity. It is able to utilize nicked circular duplex DNA as a template and can unwind the parental DNA strand from its template.

Applications

1. Western blotting (1/1,000 – 1/5,000 dilution)
2. Immunoprecipitation is assay dependent

Specification

Immunogen: Full-size recombinant E. coli DNA polymerase 1.

Reactivity: E. coli DNA polymerase 1. Not tested in other species

Form: Antiserum added with sodium azide 0.05%

Storage: Shipped at 4°C or at -20°C. Upon arrival, spin-down and store at -20°C.

4. The crude lysate of E.coli cells was reacted with anti-DNA polymerase 1 antibody and precipitated with protein G conjugated magnetic beads, and analyzed by WB by using anti-DNA polymerase 1 antibody. As the secondary antibody, anti-rabbit IgG antibody conjugated with HRP for IP (Abcam 131368) was used.
