This protein carries a polyhistidine tag at the C-terminus, and has a calculated MW of 47.1 kDa. The predicted N-terminus is Leu 23. The reducing (R) protein migrates as 55-60 kDa in 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.
