Antibody was affinity purified using an epitope specific to ErbB2 immobilized on solid support. The epitope recognized by A300-621A maps to a region between residues 975 and 1025 of human v-erb-b2 erythroblastic leukemia viral oncogene homolog 2 using the numbering given in entry NP_004439.2 (GeneID 2064). Immunoglobulin concentration was determined by extinction coefficient: absorbance at 280 nm of 1.4 equals 1.0 mg of IgG.

Detection of human ErbB2 by western blot

Detection of human ErbB2 by western blot and immunoprecipitation. Samples: Whole cell lysate from HeLa (5, 15 and 50 µg for WB; 1 mg for IP, 20% of IP loaded) and HEK293T (T; 50 µg for WB) cells. Antibodies: Affinity purified rabbit anti-ErbB2 antibody BL3030 (Cat. No. A300-621A) used for WB at 1 µg/ml (A) and 0.04 µg/ml (B) and used for IP at 3 µg/mg lysate. ErbB2 was also immunoprecipitated using rabbit anti-ErbB2 antibodies BL3031, BL3032 (Cat. No. A300-622A) and BL3033 (Cat. No. A300-623A) at 3 µg/mg lysate. Detection: Chemiluminescence with exposure times of 10 seconds (A and B).
