描述 | 产品名称:Recombinant Human CXCL12 (68AA)理论分子量:8 KDa蛋白种属:Human表达系统:E.coli蛋白表达区间:Lys22-Lys89标签:Tag free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:Stromal Cell-Derived Factor-1 (SDF-1) is a chemokine member of the intercrine family. SDF1 is expressed as five isoforms that differ only in the C terminal tail. SDF1α and SDF1β are identical except for the four residues present in the C-terminus of SDF1β but absent from SDF1α. SDF1 isoforms interact with CXCR4 and CXCR7 receptors on the cell surface, and can also bind syndecan4. SDF1 is known to influence lymphopoiesis, regulate patterning and cell number of neural progenitors, and promote angiogenesis. It also enhances the survival of myeloid progenitor cells. |
