The subunit CD3E carries a human IgG1 Fc fragment at the C-terminus, followed by a polyhistidine tag. The subunit CD3D carries a human IgG1 Fc fragment at the C-terminus, followed by a flag tag. The protein has a calculated MW of 39.2 kDa (CD3E) and 37.5 kDa (CD3D) . The protein migrates as 45-55 kDa on a SDS-PAGE gel under reducing (R) condition due to glycosylation.
>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.
