Investigation of group-specific antigen during the culture of MC-29 hepatoma.

The short-time culture established from MC-29 chicken hepatoma was used for the analysis of cell morphology and expression of avian gs antigen. The content of gs antigen was not changed during the period of cultivation. Two morphologically different types of cells were present in tested tumour cells. Fluorescent antibody test showed the presence of gs antigen in both types of cells.
