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

Streptavidin Protein - PE (STN-NP117, STN-NP119), supporting the assembly of your own MHC Tetramers!
  • Source
    Human HLA-A*03:01&B2M Monomer Protein(HLM-H52H3) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Thr 305 (HLA-A*03:01) & Ile 21 - Met 119 (B2M) (Accession # P04439 (HLA-A*03:01) & P61769 (B2M)).
    Predicted N-terminus: Gly 25 & Ile 21
  • Molecular Characterization

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 37.7 kDa and 15.7 kDa. The protein migrates as 42-45 kDa and 16 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

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

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

  • Background
    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.
