FIG. 2.

Relative osmolality as a function of intracellular solute concentration for the cytoplasms of TF-1 cells, HUVECs, porcine chondrocytes, human hepatocytes, porcine hepatocytes, and mouse oocytes. The solid line is predicted assuming the cytoplasm behaves as an ideal solution (π=m). The dashed lines are predicted assuming non-ideality of the cytoplasm using the osmotic virial equation (Equation 8) and the measured second osmotic virial coefficients (B).
