Biotinylated Human HLA-C*07:02:01&B2M Monomer Protein (Peptide free, MALS verified)

HLA-A, B, and C are transmembrane glycoproteins in the major histocompatibility complex 1 (MHC I) family. The C receptor is a heterodimer consisting of a HLA-C mature gene product (heavy chain) and β2-microglobulin (light chain) . The mature C chain is anchored in the membrane. HLA class I molecules play a central role in the immune system by presenting peptides derived from endoplasmic reticulum lumen. HLA-C are expressed in nearly all cells, and present small peptides to the immune system which surveys for non-self peptides.

Background

Specifications

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™) . The protein has a calculated MW of 36.1 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.
