Vue d’ensemble
QL9 (QLSPFPFDL) TFA is a high-affinity alloantigen for the 2C T cell receptor (TCR).
Appearance:Solid
In Vitro:Mouse T cell clone 2C recognizes two different major histocompatibility (MHC) ligands, the self MHC K b and the allogeneic MHC L d . Two distinct peptides, SIY (SIYRYYGL) and QL9 (QLSPFPFDL), act as strong and specific agonists when bind to K b and L d ,
Biological Activity:QL9 (QLSPFPFDL) TFA is a high-affinity alloantigen for the 2C T cell receptor (TCR).
Cell Assay:QL9 (QLSPFPFDL) TFA is a high-affinity alloantigen for the 2C T cell receptor (TCR).
