Other Tags and Version Biotin & Other Labeled Version
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 48.7 kDa. The protein migrates as 55-70 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method / rFC method.
Purity
>90% as determined by SDS-PAGE.
>90% as determined by SEC-HPLC.
Formulation
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.
