Measurement of affinity constant of monoclonal antibody by competitive antibody binding to antigen

以抗体竞争结合抗原测定单抗亲和力常数的研究

No heterogeneity between Jianchang duck mtDNA and Beijing duck mtDNA; Some kinds of receptors possess two affinity binding sites, they belong to the complex ligand-binding system.

家鸭很可能不存在mtDNA种内异质现象；某些受体存在着亚型或异质型，即对某种配基存在有亲和性不同的结合部位，属复杂配基&结合系统。

The affinity of Taq pol binding with DNA T-P decreased when the number of mismatched bases increased.

引物末端一个至多个的碱基错配影响了Taq聚合酶（Taq pol）和DNA模板-引物（DNA T-P）的结合，随错配碱基个数增多Taq pol和DNA的亲和力下降。

The effects of nicotine dependence in M and N cholinergic receptors ( M-and N-R) in rat brains were studied by radioligand-receptor binding assay. The results showed that after developing nicotine dependence ( 1) the affinity and density of M-R in the brains unchanged;
