Genic Determination of a Protein in the Immunoglobulin Region in the Chicken

HARRIS and Sweeney (1969) have presented the most recent in a series of studies of the serum proteins of the chicken as analyzed by electrophoresis. A series of earlier reports, Braun (1969), Glick (1968), Amin (1961a, b), Vanstone et al. (1955), have attempted to lay out procedures and to examine relationships between serum protein components and various other measures of the chicken. Lush (1961) and Ogden et al. (1962) were able to demonstrate inherited differences in albumens and transferrins in the chicken. In Braun’s (1969) report there was a suggestion of discrete variation of a small protein fraction in the immunoglobulin region, near the origin in his system. We report here on an investigation of the variation noted by Braun. MATERIALS AND METHODS The animals used in this study were White Leghorn chickens, all from one inbred line, composed of two subgroups. The birds were made available by Dr. W.…
