This protein carries a polyhistidine tag at the C-terminus. The mature form of Complement C5 is a disulfide-linked heterodimer composed of proteolytically cleaved α and β chain. Each α and β chain has a calculated MW of 73.9 kDa (β chain) and 114.4 kDa (α chain). The protein migrates as 67 kDa (β chain) and 106-116 kDa (α chain) under reducing (R) condition (SDS-PAGE), and 130-150 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
