A method for the synthesis and screening of thiol-modified peptides that are recognized by T cells is presented.

In chapter four, the energy of antigen recognition is mapped using soluble 2C TCR and the alanine-scanning mutagenesis technique. A majority of the binding energy for alloantigen recognition is derived from residues within the CDR 1 and 2 regions of the 2C TCR. Additional TCR mutants are analyzed in chapter five, including several which improve the affinity of the TCR for pMHC.
