Abstract

Antisera were raised in rabbits against two mouse monoclonal anti-porcine growth hormone (pGH) antibodies. Anti-idiotypic antibodies were isolated from rabbit sera by successive passage over immunoadsorbent columns of normal mouse Ig (mIg), followed by the specific immunizing monoclonal and elution from the latter. Enzyme linked immunoadsorbent assay (ELISA) for anti-idiotype and free idiotype were established. While showing specificity for their respective inducing monoclonals, anti-idiotypes also cross reacted in varying degrees with other anti-pGH monoclonals regardless of specificity differences between the antibodies, demonstrating the presence of a cross-reactive idiotype.

兔抗猪生长激素单克隆抗体抗独特型血清的制备及特异性表征。
兔制备了两种小鼠单克隆抗猪生长激素(pGH)抗体的抗血清。通过正常小鼠Ig (mIg)免疫吸附柱逐层传代,从兔血清中分离出抗独特型抗体,制备特异性免疫单克隆,再从正常小鼠Ig中洗脱。建立了抗独特型和游离独特型的酶联免疫吸附试验(ELISA)。抗独特型在表现出各自诱导单克隆特异性的同时,也与其他抗pgh单克隆发生不同程度的交叉反应,而不考虑抗体之间的特异性差异,表明存在交叉反应独特型。
