Anti-DNA Polymerase β Antibody (Rabbit Antiserum)


SKU: 70-041 Research Area: Applications:


DNA polymerase β is a distributive polymerase involved in base excision repair which repairs damaged DNA by excising modified bases (oxidized, methylated, deaminated etc.). It has single-strand DNA binding and deoxyribose phosphodiesterase activities on the N-terminal side, and nucleotidyltransferase activity on the C-terminal side.  The enzyme is constitutively expressed in growing cells but the level of expression is further increased by treatment with alkylating reagents such as MNNG and MMS.



Reactivity: human, rat, mouse, hamster

Validated by full-size recombinant DNA polymerase β

Form: 1 mg/ml in PBS, 50% glycerol, filter-sterilized.  Azide and carrier free

Immunogen: Recombinant rat DNA polymerase beta, functional

Storage: Shipped at 4℃ and stored at -20℃

Fig.3 Immunofluorescence staining of DNA polymerase beta in NIH 3T3 cells with the antibody. The cells were fixed with 4% PFA and permeabilized with 0.25% Triton X-100. The anti-DNA polymerase beta antibody was used at 1/1,000 dilution. Nulear DNA was stained with DAPI and the merged image was shown on the right.
