Stimulating T cells with EBV (GP350/340) Peptide pool releases downstream cytokines and upregulates activation markers, enabling antigen-specific T cells to be detected or isolated for analysis. EBV (GP350/340) Peptide pool is a lyophilised mixture of 224 peptides from envelope glycoprotein GP350 (GP350/340) of Epstein-Barr virus (EBV; strain B95-8), and consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 907 on GP350/340. GP350 meditates EBV attachment to B lymphocytes via binding to the cell surface receptor CR2 (also known as C3d receptor or CD21) (Nemerow et al.; Tanner et al.). Viral peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.
