  • RelevanceThree subregions of the Major Histocompatibility Complex (MHC), DP, DQ and DR, determine class II molecules, which are essential in the cellular recognition interactions involved in the generation of an immune response. These molecules display processed antigens from virally-infected or transformed cells. Class-II-positive cells (antigen-presenting cells) can take up antigens from outside by endocytosis, degrade them into small peptides, and re-export the peptides (now bound to MHC class II protein) to the cell surface. These peptide-MHC class II complexes can then be recognized by specific CD4+ lymphocytes. Several class II antigens are also associated with disease states. The extremely high polymorphism of MHC class II transmembrane heterodimers is due to a few hypervariable segments present in the most external domain of their alpha and beta chains. The alpha chain of MHC-DR is not polymorphic, whereas the beta chain is highly so. Some changes in amino acid sequence are critical in disease susceptibility associations as well as the ability to present processed antigens to T cells.

We unfortunately cannot provide ab20147 and ab54217 as FITC conjugated antibodies because we do not custom conjugate the antibodies.

We however have the following anti CD90 FITC conjugated antibodies that may be of your interest
