Description: M1 peptide is a synthetic peptide represents residues 58-66 of the influenza A matrix protein. In HLA-A*0201 subjects the CD8+ CTL response is dominated by cells expressing Vβ17 and responding to this peptide. Structure: The sequence of the peptide is GILGFVFTL Storage: Store frozen at ≤minus 20oC Activity: The optimum concentration depends on the specific use of the peptide. To stimulate PBMC, concentrations of 1-10 ug/mL are appropriate. Specific T cell clones and lines respond well to much lower concentrations. References Moss PA, Moots RJ, Rosenberg WM, et al.
