IRS-1抗体识别内源性的IRS-1总蛋白水平。此抗体不与IRS-2, -3或-4发生交叉反应。该多克隆抗体用与人类IRS-1蛋白羧基末端氨基酸序列对应的人工合成肽段免疫动物而制成。该抗体使用蛋白A和蛋白亲和层析纯化制得。IRS-1 Antibody detects endogenous levels of total IRS-1. It does not cross-react with IRS-2, -3 or -4. Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the carboxy-terminal sequence of human IRS-1. Antibodies are purified by protein A and peptide affinity chromatography.
