The transgene was generated by co-injection of two constructs created by separate cloning into a T-cell receptor expression vector the PCR-amplified cDNAs encoding mouse alpha-chain and beta-chain T-cell receptor subunits expressed by a CD4+ T-cell hybridoma designated Clone 1.1. The reconstituted receptor pairs with the CD4 coreceptor and is specific for chicken ovalbumin residues 323-339 in the context of H2-Ab1 (I-Ab). (J:87876)
