Recombinant Human MHC class I chain-related gene B (CRP08129)

Recombinant Human MHC class I chain-related gene B CRP08129 1mg Please Inquiry


  • Product Overview
  • Recombinant Human MIC-B produced in E.coli is a protein with 326 amino acid residues containing the extracellular domain of mature human MICB (amino acid residues Ala23 – Tyr312) and having a molecular mass of approximately 37 kDa.
  • Specificity
  • Measured by its ability to bind MICB antibody in a ELISA.
  • Endotoxin
  • Less than 1EU/μg of rHuMIC-B as determined by LAL method.
  • Purity
  • >95% by SDS-PAGE and HPLC analyses.
  • Storage
  • This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working alire 0t -C to -70°C. Avoid repeated freeze/thaw cycles.
  • Reconstitution
  • We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at <-20°C. Further dilutions should be made in appropriate buffered solutions.


  • Antigen Description
  • MIC-B (MHC class I chain-related gene B) is a transmembrane glycoprotein that functions as a ligand for human NKG2D. A closely related protein, MIC-A, shares 85% amino acid identity with MIC-B. These 2 proteins are distantly related to the MHC class I proteins. MIC-A and MIC-B (MIC-A/B) possess three extracellular immunoglobulin-like domains, but have no capacity to bind peptide or interact with β2-microglobulin. The genes encoding MIC-A/B are found within the major histocompatibility complex on human chromosome 6. The MIC-B locus is polymorphic with more than 15 recognized human alleles. MIC-A/B are minimally expressed on normal cells, but are frequently expressed on epithelial tumors and can be induced by bacterial and viral infections.MIC-A/B are ligands for NKG2D, an activating receptor expressed on NK cells, NKT cells, γδ T cells, and CD8+ αβ T cells. Recognition of MIC-A/B by NKG2D results in the activation of cytolytic activity and/or cytokine production by these effector cells. MIC-A/B recognition is involved in tumor surveillance, viral infections, and autoimmune diseases. The release of soluble forms of MIC-A/B from tumors down-regulates NKG2D surface expression on effector cells resulting in the impairment of anti-tumor immune response.
