This protein carries a mouse IgG2a Fc tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 53.2 kDa. The protein migrates as 60-66 kDa under reducing (R) 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. Normally trehalose is added as protectant before lyophilization.
