Abstract
Rabbits were immunized with a preparation of microvillus membranes derived from the absorptive cells of the small intestine of suckling rats. The resulting immune serum contained antibodies which reacted specifically with the brush borders and walls of cytoplasmic vesicles of the intestinal cells and was more effective than normal serum in preventing the transport of Ig[immunoglobulin]G across the intestinal cells. Microvillus membrane components or receptors participate in the transport mechanism.
