Application of crystallization in purification of bischofite 结晶在六水氯化镁纯化过程中的应用
Preliminary study of purification process for the production of tuberculosis dna vaccine 结核病核酸疫苗纯化过程的初步研究
The results shows that the concentration of acetylcholinesterase in earthworms was low , it was not steady and its loss during purification process was great 且纯化过程中损失较大,结果欠佳;活化载体共价结合法固定得到的乙酰胆碱酯酶酶膜活性高,酶不易损失,重现性好。
Variation of pi was related to subunits dissociation . go isozyme was unstable and its molecular weight ( mr ) , specific activity and pi decreased during purification Go同工酶在纯化过程中很不稳定,其全酶分子量( mr ) 、活性和pi均会下降,这可能是造成目前报道的go的mr和pi等基本参数相差很大的原因。
Monitoring insulin in procedure of production and purification , determining insulin content from bio - tissue fluid and single islets of langerhans , and studying insulin molecular structure are all dependent on chromatographic analysis 胰岛素制剂的纯度检验,胰岛素生产及纯化过程的监控,生物体液及胰岛细胞分泌胰岛素的状况,重组胰岛素结构的刚定及活性研究等都离不开胰岛素的测定。
