Abstract
Two strains of mice were shown to differ in relative proportion of two major protein bands of liver under acid conditions of electrophoresis. Genetic control was autosomal and by a pair of dominant and recessive genes. The difference was observed only if liver homogenates were extracted by treating with dilute acid and alkali. The two protein bands were identified as albumin on the basis of electrophoretic migration, molecular weight, and immunological response. No differences were found between strains in relative amounts of comparable bands of plasma. However, in studies with extraction of mixtures, liver homogenates of one strain but not another were capable of converting a large proportion of albumin from several sources to a faster-migrating form. It was concluded that the strains differ in a factor in liver capable of causing a secondary modification of the albumin molecule.
