Although separation techniques have been used in a variety of cellular systems, they have been particularly useful in the study of reticuloendothelial cells and primarily in the study of cells…

First, a variety of genetic and protein structural evidence suggests that two discrete genes - both a variable region gene and a constant region gene - specify each heavy chain…

Ever since arbovirus infections became known and their relative importance assessed, experiments were designed to elucidate the mode of transmission and the most important natural hosts responsible for perpetuating the…

Each control operation is mediated by a pair of complementary genetic elements (hereafter called control cell ): a control gene which produces a l control (or regulator) protein and a…

Phenomena as diverse as tuberculin sensitivity, delayed sensitivity to soluble proteins other than tuberculin, contact allergy, homograft rejection, experimental autoallergies, and the response to many microorganisms, have been classified as…
