MHC

Major histocompatibility complex (MHC) research products include peptide antigens that MHC molecules present to T cells. Class I molecules display peptides from cytosolic proteins to cytotoxic T cells, whereas class II molecules present to helper T cells. In 1974 virus-specific T cell killing was shown to require a shared MHC haplotype, known as MHC restriction. The 1987 crystal structure of human leukocyte antigen A2 (HLA-A2) revealed a peptide-binding groove between two α-helices. The chicken ovalbumin (OVA) epitope SIINFEKL is offered as OVA Peptide(257-264) TFA, a trifluoroacetate salt. It binds the mouse class I molecule H-2Kb and is used to stimulate ovalbumin-specific cytotoxic T cells. OVA (55-62) is a second ovalbumin peptide presented by H-2Kb in mouse T cell studies.

    Immunoproteasome activator 1

    Immunoproteasome Activator 1 is a selective activator of the immunoproteasome that enhances the presentation of MHC-I-bound peptides by over 100-fold. This compound functions by binding to the proteasome structural subunit PSMA1, facilitating the association of the proteasome activator PA28α/β (PSME1/PSME2) with immunoproteasomes. Its significant biological activity makes it valuable for research focused on immune response modulation and antigen processing.
