摘要: 本研究采用单因素试验设计,以紫外分光光度法测定的各处理蛋白质浓度为指标,探讨以1:1的稀释倍数,PEG6000浓度、稀释液(PBS)pH值及介质温度对鸡卵黄抗体提取的影响,结果表明:PEG6000浓度、介质温度和稀释液PBS的pH值对鸡卵黄抗体提取存在极显著的影响。稀释液PBS的pH值为7.2,介质温度为31℃左右,PEG6000浓度分别为0、1%、2%、3%、4%、5%六个处理中,以4%浓度的提取效果最好;稀释液PBS的pH值为7.2,PEG6000浓度为3%,介质温度为3、8、14、20、28、36℃六个处理中,以36℃的提取效果越好;稀释液PBS的pH值为7.2,介质温度为31℃左右,稀释液PBS的pH值分别为5.7、6.2、6.8、7.0、7.4、8.0六个处理中,pH值7.0的提取效果最好,且与pH值6.8的处理间差异不显著。

Abstract: Objective: The influences factors of drawing yolk antibody has been researched, the best environment of drawing the yolk antibody and the method of drawing the yolk antibodies the most have been look for. Methods: the yolk antibody has been drew under 1:1 dilution fold, different PEG6000 density, different temperature, under PBS of different pH values, the protein content which is also called antibody content has been measured with the ultraviolet spectrophotometer; the abstraction amount has been compared separately under different environment. Results: The PEG6000 density, environment temperature, and PBS of different pH values on extraction of yolk IgY vary remarkablely. The best density of drawing PEG6000 of the yolk antibody is about 4%, the best pH values is 7.0 and the best drawing temperature about 31 degrees centigrade,the difference between pH value 7.0 and pH value 6.8 is not notable.

Key words: egg yolk antibody, abstraction, PEG6000 density, pH value, environment temperature
