Other Tags and Version Biotin & Other Labeled Version
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 26.5 kDa. The protein migrates as 30-35 kDa under reducing (R) condition (SDS-PAGE) due to N-linked glycosylation which has been verified by PNGase F digestion.
Endotoxin
Less than 1.0 EU per μg by the LAL method / rFC method.
Purity
>90% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in Tris and Glycine, pH7.5 with trehalose as protectant.
