Description
SIIVFEKL TFA is a variant of the major MHC class I-restricted epitope SIINFEKL. SIIVFEKL TFA is an antigenic peptide, that can stimulate specific T cells in experimental settings to study the competitive interaction between T cells. SIIVFEKL TFA exhibits low affinity for the OT-I T cell receptor (TCR), and can be used for detection of CD8+ T cells[1]
