MHC expression of African green monkeys of Barbados is limited in heterogeneity

Major histocompatibility complex expression of activated peripheral blood lymphocytes of captive African green monkeys from Barbados and from Africa were analyzed biochemically; class I molecules by one-dimensional isoelectric focusing and class II DR molecules by one-dimensional nonequilibrium pH gradient electrophoresis. Much less diversity was observed in the major histocompatability molecule expression of the African green monkeys of Barbados than in the African cohort.
