In a previous blog post (How to screen SARS-CoV-2 peptides to facilitate T cell research) MBL International described how the immune system samples all of the pathogenic proteins by looking at the small fragments of each protein and determining whether
Screening for COVID-19 T-Cell Peptides and Immune Monitoring with MHC Tetramers In A Single Assay
COVID-19 infected cells can be recognized by T-cells only after SARS-CoV-2 peptides are processed and presented in the context of self MHCs. Identifying these peptides have essential utilities: Immune monitoring: Using peptide-MHC tetramers to assess vaccine-induced immunity Designing potent vaccines
Tetramers
TCRs recognize and bind to complexes composed of MHC molecules and specific peptides expressed on the surface of antigen-presenting cells. While it was once believed that antigen-specific T cells could be detected using soluble MHC/peptide complexes, monomeric MHC/peptide complexes proved
MHC Class I & II Tetramers, MHC Monomers and CD1d Tetramers
TCRs recognize and bind to complexes composed of MHC molecules and specific peptides expressed on the surface of antigen-presenting cells. We have tetramerized and biotinylated with streptavidin to maintain stable binding to multiple TCR, enabling MHC/peptide tetramers to be used
Monomers
Biotinylated MHC monomers, the building blocks of MHC tetramers, are now available for tetramer construction flexibility and novel applications. See All Monomer Products
CD1d
CD1d is a membrane protein non-covalently bonded to β2-microglobulin (β2m) and shows high homology between human and mouse. CD1d can present α-galactosylceramide (α-GalCer), a glycolipid extracted and isolated from the marine sponge, and this complex can activate human and murine
