Request for sequenceMolecular Characterization
Other Tags and Version Biotin & Other Labeled Version
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 17.3 kDa. The protein migrates as 20-25 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 0.01 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 PBS, pH7.4 with trehalose as protectant.
