我们用离子交换层析和亲和层析的方法提纯了视网膜S抗原和光感受器间维生素A类结合蛋白(interphotoreceptor retinoid—bindingprotein,IRBP),分析了它们的氨基酸组成及其含量,发现绝大多数氨基酸含量与国外报道的结果相似,对个别氨基酸含量出现较大差别的可能原因及有关问题进行了讨论.
We purified the retinal S antigen and interphotoreceptor retinoid-bindingprotein (IRBP) by ion-exchange chromatography and affinity chromatography, analyzed their amino acid composition and content, and found that most of the amino acid content Similar to the results reported abroad, the possible causes for the large differences in individual amino acid content and related issues were discussed.
