This protein carries no "tag".
The protein has a calculated MW of 19.7 kDa. The protein migrates as 37 kDa±3 kDa under reducing (R) condition, and 39 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
