This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 22.1 kDa. The protein migrates as 27-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>90% as determined by reduced SDS-PAGE.
>90% as determined by SEC-HPLC.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
