This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 46.5 kDa. The protein migrates as 50-55 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
>90% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
