Abstract
Soluble extracts were prepared from cells of Brown Norway (BN) rat spleens by sonication in 2 M KI. Extracts were fractionated by gel filtration and electrophoretic procedures. The fractions specifically inhibited the binding of Lewis alloantibodies to target BN cells in vitro and in vivo. A homogeneous component that retained antigen activity was obtained by preparatory polyacrylamide gel electrophoresis. Lewis rats injected with BN antigen fractions produced histocompatibility alloantisera that would prolong the survival of BN skin grafts applied to Lewis neonates.Keywords
