CH strain chickens selected from the F2 progeny of a cross between CH (B10/10) and B14B (B14/14) strains carried bursa (BA) and thymus (TA)-specific alloantigens of B14B parental origin. The BA marker was present on 95% of bursal cells but only on 10% of splenic and blood B lymphocytes. The TA marker was expressed by 80% of thymus cells and weakly by 45% of splenic and 70% of blood T lymphocytes. The adopted immunological and genetic protocol offers a feasible approach towards detection of differentiation antigens in major histocompatibility complex-homozygous but 'minor' alloantigen-segregating populations.

Chicken IgM antibodies raised against sheep erythrocytes (SE) reacted with a heterophile carbohydrate antigen designated as "HC". This antigen was visualized by SE rosette formation with antibody-sensitized and formaldehyde-fixed target cells. Cells from eight lymphoblastoid lines and ten lines of diverse histogenetic origin all expressed HC on their surface to a greater or lesser degree when grown in fetal calf serum (FCS). Lymphoblastoid cell lines, HSB2 and Namalva, lost most of their HC antigen after three cell divisions when grown in medium which contained normal human serum (NHS) instead of FCS. The acquired origin of HC was demonstrated by the conversion of HSB2-HC- into HSB2-HC+ cells after incubation in the presence of FCS or fetuin for 18 h at 37 degrees C. The acquisition of HC antigen depended on the concentration of fetuin as well as the time and temperature of incubation. The presence of NHS in the culture medium reduced the degree of HC incorporation. The level of HC expressed on the cell surface was reduced by treating HSB2 cells with sodium periodate but not by proteolytic enzymes. Competitive inhibition with hog blood group substance and sheep IgG suggested similar specificity of HC on target cells which had been sensitized with either fetuin or sheep IgM (Eur. J. Immunol. 1977.7:204). The avidity of chicken antibodies to HC in either of these systems was several orders of magnitude lower than the binding to SE.
