 Two plasmids , one containing the amino terminus of P fused to the DNA - binding domain of the yeast transactivator , GAL4 , and the other containing the amino terminus of NP fused to the herpesvirus transactivator , VP16 , were transfected in COS - 1 cells along with a chloramphenicol acetyltransferase ( CAT ) reporter plasmid containing GAL4 DNA - binding sites .
chloramphenicol acetyltransferase

 Presently , we made chain pair switch , chimeric , and site mutant gamma delta TCRs and transfected them into TCR - mutant Jurkat T cells to examine the effects of changing the TCR gamma junctional region sequences on reactivity to prenyl pyrophosphate Ags .
