Synthesis of peptides related to hydra head activator (HA; pGlu-Pro-Pro-Gly-Gly-Ser-Lys-Val-Ile-Leu-Phe-OH) was performed by the solution method. The analogs synthesized were Tyr11-HA, des-Phe11-HA, Arg1-HA and Phe5-HA. Antisera were prepared by immunizing three rabbits with the synthetic HA. Two anti-HA-antisera with sufficient titer were obtained. An HA-radioimmunoassay system, developed by using an antiserum (ASH-04) and 125I-Tyr11-HA as a tracer, was found to be sensitive and specific to HA.
与水螅头激活因子(HA; pGlu-Pro-Pro-Gly-Gly-Ser-Lys-Val-Ile-Leu-Phe-OH)相关的肽合成采用溶液法。合成的类似物包括Tyr11-HA、des-Phe11-HA、Arg1-HA和Phe5-HA。通过免疫三只兔子制备了抗血清,使用合成的HA进行免疫,获得了两个足够滴度的抗HA抗血清。利用抗血清(ASH-04)和125I-Tyr11-HA作为示踪物开发的HA放射免疫测定系统被发现对HA具有高度敏感性和特异性。
