Molecular Characterization

Online(Tyr 18 - Arg 751) K0BRG7-1Development Suggestion
This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 83.1 kDa. The protein migrates as 90-116 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method.

Purity

>95% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
