Rearranged Blo t 5 peptide 55-70 (from the storage mite Blomia tropicalis) specific T cell ValphaJalpha and VbetaD&betaJbeta genes were cloned into pTalpha and pTbeta cassettes. Transgenic constructs generated from these cassette vectors, contain the alpha-chain and beta-chain of the T-cell receptor from a T cell hybridoma clone> (J:237613)
