This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 16.8 kDa. The protein migrates as 35-45 kDa under reducing (R) condition (SDS-PAGE) due to different glycosylation.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
