| 摘 要： | 利用凝胶排阻层析-火焰原子吸收光谱法研究了Ag+在照相明胶中分子量的分布情况.研究表明,利用葡聚糖凝胶G-75可有效的将明胶中的γ、β、α及小分子蛋白L组分分开.发现Ag+完全分布于分子量较小的α大分子蛋白组分.γ组分、β组分中均不存在Ag+.

| Abstract: | The distribution of Ag+ in gelatin with respect to molecular weight was studied using gel exclusion chromatography? flame atomic absorption spectroscopy. Firstly, several gels used for isolating gelatin protein components were studied and the result indicated that dextran G-75 was favourable for the present study. The γ, β, α and other lower molecular weight components of gelatin could be isolated from each other by means of gel G-75. The results demonstrated that the Ag+ in gelatin was combined only with the α protein component and not with the γ or the β components. |
