USAGE
Reconstitute in sterile PBS, pH7.2-pH7.4.
STORAGE AND STABILITY
Storage: Avoid repeated freeze/thaw cycles. Store at 2-8oC for one month. Aliquot and store at -80oC for 12 months.
Stability Test: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37oC for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition.

还有一个优点,该细胞属于成纤维细胞(fibroblast),是一种非分泌型细胞,它本身很少分泌CHO内源蛋白,因此对目标蛋白分离纯化工作十分有利。2、CHO细胞血清培养 传统上CHO细胞的培养都是在DMEM/F12基础培养基中添加5~10的小牛血清(用于重组蛋白)或胎牛血清(用于杂交瘤生产)单抗来完成的,血清除了供给细胞的营养成分外,还能促进细胞开始合成DNA,对细胞的增殖有很大的作用。实验证明,血清在细胞的体外培养中提供了细胞增殖所必需的生长因子。但哺乳动物的血清价格昂贵,成本高不适于今天的大规
