This protein carries no "tag".
The protein has a calculated MW of 14 kDa (monomer). As a result of glycosylation, the protein migrates as 19 kDa and 20kDa under reducing (R) condition, and 40-45 kDa (homodimer) under non-reducing (NR) condition (SDS-PAGE).
>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.
