This protein carries a human IgG1 Fc tag at the N-terminus.
The protein has a calculated MW of 76.7 kDa. The protein migrates as 120-140 kDa 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 50 mM Tris, 100 mM Glycine, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.
