Biotinylated Human HLA-A*03:01&B2M Monomer Protein (Peptide free, MALS verified)

Major histocompatibility complex (MHC), group of genes that code for proteins found on the surfaces of cells that help the immune system recognize foreign substances. MHC proteins are found in all higher vertebrates. In human beings the complex is also called the human leukocyte antigen (HLA) system.

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 40-45 kDa and 12 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
