Abstract:
After cell fusion, polykaryocytes and heterokaryocytes were separated from single cells by a calf serum gradient. Fractions enriched with polykaryocytes were thus obtained. Heterokaryocytes with a prevalence of nuclei from either parental cell were distributed in different fractions of the gradient. The efficiency of the separation procedure is evaluated and its possible application to problems in cell hybridization techniques is discussed.
