DNA constructs carrying functionally rearranged anti-hen egg lysozyme (HEL) TCR Valpha11 andVbeta3 chain genes were obtained from a HEL-specific T cell hybridoma BO4H9.1 which recognizes a subdominant but not cryptic peptide of HEL and injected in fertilized eggs. This line is derived from one of the two founders created. (J:116743)
