“…It is possible to ascertain, by means of immunoelectrophoresis of their gastric contents, whether mosquitoes have fed upon humans or animals (691). Immunoelectrophoretic investigations of clinical interest include studies of proteins in relation to neoplasms (96, 320, 684, 855), abnormal proteins (51,97,111,263,321,362,369,387), arthritis (144, 145, 146, 174, 175, 220, 500), atherosclerosis (42), hereditary hemolytic disorders (576), nephrosis (656), diabetes (800), lupus (44), leprosy (83), skin diseases (364), tuberculosis (521), hepatitis (88, 114, 125), and rickettsia antigens (288). Miscellaneous applications include studies of fetal proteins in rats (424) and humans (577), studies of specific proteins in an electrophoretically homogeneous group (441,604, 666, 667), of complement (292), of proteins following the incorporation of C14-labeled amino acids (199), and of specific immune substances including antiglobulins (400), isohemagglutinins (397), and antibodies against pertussus (836), brucellosis (395), and Candida albicans (94) LITERATURE CITED…”
