Abstract
Considerable amount of complexes, formed after binding of 3H-alanine and 125I-diiodotyrosine with blood serum proteins in vivo and in vitro was found to dissociate as a result of gel filtration on microcolumns of Sephadex G-25 in presence of 8 M urea. The phenomenon observed may be considered among possible reasons responsible for overestimation of the adsorption rate of food proteins antigens in gastrointestinal tract of experimental animals.
摘要
体内和体外实验发现，3H-丙氨酸和125I-二碘酪氨酸与血清蛋白结合后形成的大量复合物，在8M尿素存在的情况下通过Sephadex G-25微柱凝胶过滤会发生解离。观察到的这种现象可能是导致实验动物胃肠道中食物蛋白抗原吸附率被高估的潜在原因之一。
