Other Tags and Version Biotin & Other Labeled Version
The product does NOT contain any epitope tags. The protein has a calculated MW of 14.5 kDa. The protein migrates as 18-28 kDa on a SDS-PAGE gel under reducing (R) condition due to glycosylation.
Labeling
The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product.
Protein Ratio
Passed as determined by the HABA assay / binding ELISA.
Purity
>95% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
