The Mixed Agglutination Test in Studies on Human Transplantation

Abstract
Mixed agglutination with cell cultures was originally described by Högman1 and by Fagraeus and Espmark.2 In this laboratory, application of this procedure for various research purposes3-10 was explored. One promising line seemed to be the detection of humoral antibodies accompanying homograft rejection in mice, rats, and rabbits.7-10 In the present paper, preliminary studies on the demonstration of antibodies appearing as a result of homograft rejection in humans, as well as studies on human tissue typing will be reported. Materials and Methods Human Cell Lines.— HeLa,11 AV-3,12 WI-38,13 HEp-2,14 D-6,15 and KB16 cells were cultured as described previously3,4 and studied when a whole monolayer was developed, usually after seven days of incubation. Primary cell cultures were set up from human tonsils. The tissues were obtained from Children's Hospital, Buffalo, immediately after tonsillectomy. In preparing cell cultures, previously described methods3,4
