    CTLA-4 was first isolated as a gene by reverse genetics using a cDNA subtractive hybridization followed by serial differential hybridization screenings. CTLA-4 belongs to lymphocyte activation antigens which express transiently on T cell surface when it is activated. The nature of this molecule has made it difficult to develop anti-CTLA-4 specific antibody and to characterize protein counter part of this molecule. Here we describe a method to produce anti-human CTLA-4 antibody by immunizing with synthetic peptide coupled to Keyhole Limpet hemocyanin. In western blot 3 anti -peptide antibodies showed titers between 1:800 & 1:1,600. These 3 different anti-peptide antibodies recognized 34kD band as human CTLA-4 protein in western blot. It was found that humanNK and CD8+ T cell clone, LOH and NBL77 could produce CTLA-4. Polyclonal mitogenic combinations, PHA, PMA+ionomycin, SEB, anti-CD2 antibodies 9.1+9.6, and MLC with allogenic EBV transformed B cell, could induce CTLA-4 expression in peripheral blood lymphocyte which peaked on day 3 by PHA and anti CD2 stimulation and on day 5 by PMA+ionomycin and SEB stimulation. And IL-2 was able to increase CTLA-4 induction in MLC.
