Tg(CAG-OVAL)916Jen

The transgene consists of a full-length chicken ovalbumin cDNA preceded by the 5' leader sequence of the mouse H2-Kb gene and followed by the DNA sequence encoding the short extracellular spacer and transmembrane domain of the mouse H2-Db gene joined to the rabbit beta-globin polyadenylation signal; its expression is driven by the chicken beta-actin promoter under control of the CMV immediate early enhancer. Ovalbumin expression was detected immunohistochemically on the surfaces of cells of all organs and shown to function in skin-graft experiments as a minor histocompatibility antigen that triggered graft rejection by a mechanism involving both CD4 and CD8 T lymphocytes.
