Peptides are continuously exposed in MHC class I molecules at the cell surface. These MHC–peptide complexes are recognized by circulating lymphocytes. If the presented antigen peptide is not self-derived it leads to an immune reaction. We offer antigen peptides and MHC multimers to profile antigen-specific immune responses.
COVID-19 antigen peptides represent specific SARS-CoV-2 epitopes for antigen-specific T cell in functional T cell assays such as ELISpot.
Antigen peptides represent specific epitopes for stimulation of T cells in interferon gamma releasing T cell assays such as ELISpot.
