蛋白浓缩（protein－concentration）基本方法
蛋白浓缩方法基本有：丙酮沉淀法；免疫沉淀法；三氯醋酸沉淀法；硫酸铵沉淀法；（低温）有机溶剂沉淀法；聚乙二醇沉淀法；超滤法；透析法；离子交换层析和冷冻干燥法…… 1.丙酮沉淀法；三氯醋酸沉淀法 试验要求的仪器简单，但是常常导致蛋白质变性。 2.免疫沉淀法：得有特异性抗体！ 3.硫酸铵沉淀法
蛋白浓缩(protein－concentration)方法详解
1，透析袋浓缩法利用透析袋浓缩蛋白质溶液是应用最广的一种。将要浓缩的蛋白溶液放入透析袋（无透析袋可用玻璃纸代替），结扎，把高分子（6000－12000）聚合物如聚乙二醇（碳蜡）、聚乙烯吡咯、烷酮等或蔗糖撒在透析袋外即可。也可将吸水剂配成30%－40%浓度的溶液，将装有蛋白液的透析袋放入即可。吸水剂用
