Human CD55 (C-6His, HEK293)/人CD55蛋白(C-6His, HEK293) 生物活性
描述
CD55 is a member of the RCA (regulators of complement activation) family. RCA proteins is characterized by the presence of four to 30 SCRs (short consensus repeats also called CCPs for control protein modules) in their plasmaexposed regions. CD55 containing four SCR modules is involved in the regulation of the complement cascade. CD55 is known to bind CD97 via the first SCR. It also binds physiologically generated C3 convertases with its second and third SCRs. Binding results in an accelerated “decay”, or dissociation of active C3 convertases, thus blocking the development of C’ attack complexes on nonforeign cells. It is known that viruses and bacteria also utilize multiple SCR sites for infection.
Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4.
复溶
Always centrifuge tubes before opening.Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.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。
