鮭魚/鱒魚IGF-II抗體通過用對應于成熟大西洋鮭魚N-末端氨基酸殘基1 - 9的合成肽表位免疫兔來制備( 鮭)胰島素樣生長因子-II。收獲抗血清,并通過疏水電荷誘導層析部分純化IgG級分。該抗體對來自大西洋鮭魚和虹鱒魚的IGF-II具有高度特異性( 梅氏虹鱒)在酶聯免疫測定中。與鮭魚胰島素的交叉反應性約為5%,<0.01%對鮭魚IGF-I和鮭魚GH的影響。 nSalmon/Trout IGF-II antibody was prepared by immunising rabbits with a synthetic peptide epitope corresponding to amino acid residues 1-9 of the N-terminus of mature Atlantic salmon (Salmo salar) IGF-II. The antiserum was harvested and the IgG fraction partially purified by hydrophobic charge induction chromatography. The antibody is highly specific for IGF-II from Atlantic salmon and Rainbow trout (Oncorhynchus mykiss) in an enzyme-linked immunoassay. It has a cross-reactivity of ~ 5% to salmon insulin and < 0.01% to salmon IGF-I and salmon GH.
