This protein carries a polyhistidine tag at the N-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 22.4 kDa (monomer). As a result of glycosylation, the protein migrates as 25-33 kDa (monomer) under reducing (R) condition, and 42-55 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.
