T-cell hybrids. IV. One of parental cell lines is dominant in determining membrane characteristics of hybrid cells.

: Membrane characteristics of parental thymic lymphoma cells (BW5147, EL-4R) and their hybrids (BH2) derived by PEG-promoted cell fusion were compared. Isoelectric focusing of the cell populations, titration of membrane proton binding groups and quantitative examination of cell-substrate adhesiveness indicated that the BW5147 cells behaved as dominant in determining cell membrane characteristics of the BH2 hybrids.
