近年来,用放射受体法研究激素与受体的相互作用取得不少进展。用同位素标记的凝集素测定细胞表面膜的凝集素受体,文献也有不少报道,其中尤以ConA为材料者较多,但多数结果不能说明受体与凝集素强度之间有对应关系。不过,这些数据都是用饱和分析法测定细胞与ConA的最大结合量,而未作受体与ConA间结合常数(Ka)的测定,可是Ka是受体分析中最关重要的一项数据。因为专一 In recent years, the use of radioactive receptor method to study the interaction of hormones and receptors made a lot of progress. Lectins labeled with isotope labeled cell surface membrane lectin receptors, there are many reports in the literature, especially in ConA materials are more, but most of the results can not explain the receptor and the relationship between the strength of the lectin. However, these data are based on saturation analysis to determine the maximum binding of cells to ConA, without the determination of the binding constant (Ka) between the receptor and ConA, but Ka is the most critical data for receptor analysis. Because of specificity
