Western blot analysis was performed on whole cell extracts (30 µg lysate) of Daudi (Lane 1), K-562 (Lane 2), NIH/3T3 (Lane3), SH-SY5Y (Lane4) and tissue extract (30 µg lysate) of Rat Testis (Lane 5).The blots were probed with Anti-DNA Polymerase beta Mouse monoclonal Antibody (Product # MA5-12086, 2 µg/ml) and detected by chemiluminescence using Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, HRP conjµgate (Product # A28177, 0.4 µg/ml, 1:2500 dilution). A 38 kDa band corresponding to DNA Polymerase beta was observed across the cell lines tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 10 % Bis-Tris gel (Product # NP0302BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® 2 Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody following blocking with 5% skimmed milk. Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

MA5-12086 targets DNA Polymerase beta in WB applications and shows reactivity with Human samples.
The MA5-12086 immunogen is dNA polymerase beta protein.
DNA polymerase beta comprises an amino-terminal 8-kDa domain and a carboxy-terminal 31-kDa domain. The N-terminal ssDNA binding domain has a deoxyribose phosphodiesterase activity while the C-terminal domain has a nucleotidyltransferase activity. Mammalian DNA polymerase beta, a DNA repair polymerase, is constitutively expressed in cultured cells, but treatment of cells with the DNA-alkylating agents such as N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) or methyl methanesulfonate up-regulates beta-pol level. DNA polymerase beta fills single nucleotide gaps in DNA produced by the base excision repair pathway of mammalian cells.
