MABSol® Biotinylated Human Her2, His Tag, primary amine labeling, long spacer (HE2-H822R) is expressed from human HEK293 cells. It contains AA Thr 23 - Thr 652 (Accession # P04626-1). It is the biotinylated form of Human Her2, His Tag (Cat. No. HE2-H5225).

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 specially optimized long-spacer biotin reagent (32.5 angstroms) is used in this product to minimize potential steric hindrance.

Passed as determined by the HABA assay / binding ELISA.

Less than 1.0 EU per μg by the LAL method / rFC method.

>95% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
