Presence of Alloreactive Ia Antigens on Murine Intestine Epithelial Cells

Abstract
Purified intestine epithelial cells express la antigens as determined by immunoprecipitation and sodium dodecyl sulphate polyacrylamide‐gel electrophoresis. The intestinal la antigens react at least with alloantisera directed against the H‐2 I‐A subregion.
