Sacharose density gradient separation of Ehrlich ascites carcinoma and L-5178Y tumor cells in different cell cycle phases.
Optimal conditions were determined for the distribution of Ehrlich ascites carcinoma (EAC) and L-5178Y mouse tumor cells, proliferating in vivo, by their age within the cell cycle by sedimentation in a buffered linear sacharose density gradient. Measurements of cell size, DNA content and incorporation of tritiated thymidine in successive parts of the gradient confirmed the actual separation of cells of different age: in the upper fractions there were cells in G1 phase, in the middle fractions in S phase and in the lower layers of the gradient there were cells in G2 and/or M phase.
