This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 14.9 kDa. As a result of glycosylation, the protein migrates as 17 kDa and 20 kDa under reducing (R) condition, and 35-45 kDa under non-reducing (NR) condition (SDS-PAGE).
>95% as determined by reduced SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
