该BRCA1抗体可以检测内源性BRCA1总蛋白。人类BRCA1蛋白有五种亚型,通过选择性剪切和选择性启动产生。该抗体可识别核亚型1、2和4,但是不能识别胞浆亚型3和5。该抗体不识别BRCA2蛋白。该多克隆抗体是由合成的人源的针对BRCA1蛋白氨基末端肽段免疫动物,利用A蛋白和多肽亲和层析方法纯化生产的。BRCA1 Antibody detects endogenous levels of total BRCA1 protein. Five human isoforms are produced by alternative splicing and alternative initiation. The nuclear isoforms 1, 2, and 4 are detected, whereas the cytoplasmic isoforms 3 and 5 are not. The antibody does not recognize BRCA2.Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to amino acids near the amino terminus of human BRCA1. Antibodies are purified by protein A and peptide affinity chromatography.
