We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.Reference:

层析复性蛋白质 李明1 苏志国1 Janson Jan-Christer2 (1 生化工程国家重点实验室,中国科学院过程工程研究所,北京,100080 2 表面生物技术系,Uppsala 大学,Uppsala, 瑞典) 摘要在生物学和生物医学中,尤其在制药行业中,蛋白质的体外折叠复性是一个比较棘手的问题。最近利用层析方法复性成为研究的热点,本综述主要介绍层析复性方法的进展。 随着基因工程和生物技术的发展,蛋白质克隆与表达已经趋于成熟。在重组蛋白质生产的过程中,目标产物的异源
剂如Triton X-100、脱氧胆酸盐和低浓度的变性剂如尿素充分洗涤去除杂质,这一步很重要,因为大肠杆菌外膜蛋白Omp T(37 KDa)在4-8mol/L尿素中具有蛋白水解酶活性,在包涵体的溶解和复性过程中可导致重组蛋白质的降解。 对于尿素和盐酸胍的选择: 尿素和盐酸胍属中强度变性剂,易经透析和超滤除去。它们对包涵体氢键有较强的可逆性变性作用,所需浓度尿素8-10M,盐酸胍6-8M。尿素溶解包涵体较盐酸胍慢而弱,溶解度为70-90%,尿素在作用时间较长或温度较高时会裂解形成氰酸盐,对重组蛋白质的氨
