Tissue typing by unidirectional mixed lymphocyte culture. I. Demonstration of the cumulative effect of non-H-2 antigens in mice by cultured lymphocytes mixed with cell homogenate

Abstract

1. The mixed lymphocyte culture test where live lymphocytes of female mice are cultured with supersonicated cell homogenate of isogeneic male mice does not reflect the difference in H-Y histocompatibility antigen alone. 2. When non-H-2 antigens are cumulated in various combinations, the rate of blastformation becomes greater than the combination of C3H &#9792; themselves. 3. When non-H-2 antigens and H-Y antigens are added in various combinations, the rate of blastformation becomes significantly higher than in the combination of C3H &#9792; themselves.</p
