日本对虾血清三类免疫球蛋白样物质的研究

采用单向免疫扩散法（SRID）和免疫酥斑点法（Dot-ELISA)对日本虾（Penaeus japonicus)血清中类IgM，IgG,IgA样物质进行了系统的研究分析。结果发现，虾血清中存在能与羊抗人IgM,IgG,IgA发生结合且能被特异性阻断试验确证的物质。文中还对12例对虾血清类IgM,IgG,IgA样物质的含量进行了检测。结果显示，虾血清中确实存在与人免疫球蛋白（Ig）特异性抗原决定簇极为相似的物质，它的存在对研究虾的抗病机制具有重要意义。

STUDY ON THREE CLASSES OF IMMUNOGLOBULINLIKE COMPONENTS IN Penaeus japonicus

Both methods of single radial immunodiffusion(SRID) and dot-EII SA were used to characterize three kinds of immunnoglobulin-like proteins (IgM, IgG and IgA) in serum of Penaeus japonicus. The results showed that there were components reacted with anti - human μ, γ or achain in the serum, which could be blocked by specific tests. Furthermore, the IgM- like, IgG - like and IgA - like components were measured in 12 cases of Penaeus japonicus. These findings suggest that there were materials with similar isotopes in serum from both the shrimp and human. And Ig - like proteins in the shrimps were important to understand their disease-free mechanism.
