This protein carries a polyhistidine tag at the C-terminus. This protein contains a furin convertase cleavage site, 737-RKRR-740, and will be partially processed into N (α chain) and C-terminal fragment (partial β chain) with calculated MW of 81.0 kDa and 23.8 kDa respectively. The protein migrates as 35-45 kDa (partial β chain), 110-120 kDa (α chain) and 130 kDa (α chain & partial β chain) under reducing (R) condition (SDS-PAGE) due to glycosylation.
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
