The tetratriacontapeptide corresponding to sequence 112-145 of the β-subunit of human chorionic gonadotropin (hCG) was synthesized by assembling peptide fragments by the azide procedure, followed by TFA treatment and catalytic hydrogenation. This peptide was conjugated with bovine serum albumin (BSA). New Zealand white rabbits were immunized with the conjugated antigen in Freund's complete adjuvant. Antiserum capable of 30% specific binding of 125I-hCG or 125I-β-subunit of hCG at a dilution of 1 : 5000 was produced.
通过
叠氮法组装肽片段,然后经反式
脂肪酸处理和催化氢化,合成了对应于人绒毛膜
促性腺激素(hCG)β亚基序列 112-145 的四三位一体肽。该肽与
牛血清白蛋白(
BSA)共轭。新西兰白兔在弗罗因德完全佐剂中接合抗原进行免疫。在 1 : 5000 的稀释度下,产生的抗血清能与 125I-hCG 或 hCG 的 125I-β 亚基产生 30% 的特异性结合。
