This protein carries no "tag".
The protein has a calculated MW of 14.5 kDa. The protein migrates as 18-26 kDa under reducing (R) condition (SDS-PAGE) due to 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.
