in this report , we show that a peptide fragment of the soluble globular protein antigen tobacco hornworm moth cytochrome c , residues 92-103 containing an additional nh2-terminal cysteine residue ( thmccys92-103 ) , is effectively presented by b cells to an i-ek-restricted , thmc-specific t cell hybrid when covalently coupled to antibodies specific for b cell surface ig , ia ( ak ) , or class i ( kk ) .
