作为免疫沉淀反应的假说或模式,至少应能解释在抗体过量时抗原的完全沉淀及区带现象。在探讨免疫沉淀机理的过程中,这是一个难题。人们普遍接受Heidelberger和Marrak的观点。认为沉淀性抗原抗体复合物是由抗原的表位与抗体的互补位之间,以各种键结合在一起的抗原抗体分子交替的大分子品格。然而,现在已有证据表明,这种观点不能完全解释免疫沉淀。从理论上讲,复合物分
Hypotheses or patterns of immunoprecipitation should at least explain the complete precipitation and banding of the antigen in the presence of excess antibody. This is a difficult problem in exploring the mechanism of immunoprecipitation. People generally accept the views of Heidelberger and Marrak. The precipitating antigen-antibody complex is considered to be a macromolecular character that alternates between epitopes of an antigen and the paratope of an antibody, and antigen-antibody molecules bound together by various bonds. However, there is now evidence that this view does not fully explain immunoprecipitation. In theory, the complex points
