This antibody is suitable for western blotting, immunoprecipitation, and ELISA. This antibody detects mouse Mcl-1 and is not expected to cross react with the human sequence. Cross reactivity with Mcl-1 from other sources is unknown. This antibody is highly specific, showing no bands in null cell lysates from Mcl-1 knockout mice even when grossly over-exposed. Mouse Mcl-1 (myeloid cell leukemia sequence 1) is composed of 331 amino acids and is reported to be 35.2 kDa in size. The human ortholog consists of 351 amino acids and is reported to be 37.3 kDa in size.
