蛋白质的分离纯化,尤其酶的分离纯化,在生化研究中占有极重要的地位,是生化研究的基础之一. 沉淀法分离蛋白质,早期生化研究中已经出现,其分辨率高,至今仍是生化研究中广为采用的分离蛋白质的基本手段. 它可以大量地制备较纯的蛋白质,操作过程费用低廉,蛋白质不易变性且所用试剂无毒害作用.醇脱氢酶除了在食品等工业中的作用之外, 其在科学研究和分析测定中也具有重要价值, 是酶法测定乙醇或乙醛含量的工具酶. 沉淀法和层析法至今仍是广泛采用的分离蛋白质和酶的重要手段. 用离子交换层析、亲和层析等方法经过4~5 个纯化步骤后,分离纯化ADH 和其它蛋白质,纯化倍数可达100多倍.我们从酵母细胞中分离出醇脱氢酶,并通过硫酸铵分段盐析、凝胶层析以及离子交换层析对该酶进行纯化,用较少的步骤得到了相对高的纯化倍数.

.The separation of protein purely turns and particularly the separation of Mao purely turn, occupy an of vital importance position in the bio-chemical the research, is one of the foundation of bio-chemical research. Precipitate method separation protein, in early days bio-chemical research medium have already appear, its resolution Gao, up to now was still a bio-chemical research in wide is adoption of separate protein of basic means. It can in large quantity make more pure protein, operation process the expenses be cheap, protein not mutability and use to try one not poisonous harm a function.The Chun takes off hydrogen Mao in addition to waiting the function in the industry in the food, it also has in science the research with the analysis the measurement importance value, is the tool Mao that the Mao method measureses ether or acetaldehyde content. Separation protein and the important means of Mao precipitated method and layer Xi method to up to now is still to extensively adopt.
