Antibody was affinity purified using an epitope specific to BTF immobilized on solid support. The epitope recognized by A300-610A maps to a region between residue 875 and the C-terminus (residue 920) of human BCL2-Associated Transcription Factor 1 using the numbering given in entry NP_055554.1 (GeneID 9774). Immunoglobulin concentration was determined by extinction coefficient: absorbance at 280 nm of 1.4 equals 1.0 mg of IgG.

Detection of human BTF by western blot and immunoprecipitation. Samples: Whole cell lysate (5, 15 and 50 µg for WB; 1 mg for IP, 20% of IP loaded) from HeLa cells. Antibodies: Affinity purified rabbit anti-BTF antibody BL2523 (Cat. No. A300-610A) used for WB at 0.04 µg/ml (A) and 1 µg/ml (B) and used for IP at 3 µg/mg lysate (B). BTF was also immunoprecipitated using rabbit anti-BTF antibodies BL2521 (Cat. No. A300-608A) and BL2522 (Cat. No. A300-609A) at 3 µg/mg lysate. Detection: Chemiluminescence with exposure times of 30 seconds (A) and 3 seconds (B).
