Biotinylated Human HLA-C*08:01&B2M Monomer Protein (Peptide free, MALS verified)

表达区间及表达系统（Source）

Biotinylated Human HLA-C*08:01&B2M Monomer Protein (HLM-H82Es) is expressed from human 293 cells (HEK293). It contains AA Cys 25 - Ile 308 (HLA-C*08:01) & Ile 21 - Met 119 (B2M) (Accession # QOC77848.1 (HLA-C*08:01) & P61769 (B2M)).

Predicted N-terminus: Gly 25 & Ile 21

蛋白结构（Molecular Characterization）

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

The protein has a calculated MW of 36.4 kDa and 11.7 kDa. The protein migrates as 40-43 kDa and 10 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记（Labeling）

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

蛋白标记度（Protein Ratio）

Passed as determined by the HABA assay / binding ELISA.

内毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method.

纯度（Purity）

>90% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

制剂（Formulation）

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