描述 | 产品名称:Recombinant Human CD19 (C-Fc)理论分子量:57.3 KDa蛋白种属:Human表达系统:CHO Stable Cells蛋白表达区间:Pro20-Lys291标签:C-Fc剂型:干粉纯度:≥95% as determined by reducing SDS-PAGE.储存条件:冻干蛋白应储存在≤-20°C,收到后可稳定保存一年。 溶解后的蛋白溶液可以在2-8°C下保存2-7天。如要长期保存,建议使用含载体蛋白(如 0.1%BSA、10%FBS、5%HSA)的溶液进一步稀释,如果是做无血清培养或者动物体内实验时,细胞因子中不能含有BSA、FBS 和 HAS,可以使用海藻糖作为载体,然后分装冻存于-20℃至-80℃。注:分装保存时建议使用低吸附的管子,并避免反复冻融;稀释分装浓度不低于 10μg/mL,分装体积不低于10μL。 分装后的蛋白在≤-20°C 下可稳定保存 3 个月。产品背景:CD19 is a single-pass type I membrane protein containing 2 Ig-like C2-type (immunoglobulin-like) domains. CD19 is expressed on follicular dendritic cells and B cells. In fact, it is present on B cells from earliest recognizable B-lineage cells during development to B-cell blasts but is lost on maturation to plasma cells. CD19 primarily acts as a B cell co-receptor in conjunction with CD21 and CD81. Upon activation, the cytoplasmic tail of CD19 becomes phosphorylated, which leads to binding by Src-family kinases and recruitment of PI-3 kinase. CD19 Assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation. |
