Fig. 5. (A) Correlation plots between domain area and the number of receptors contained in each domain for IL2R
(
) and IL15R
(
) for all images analyzed. The dotted lines are the lines of best fit to the correlation plots and suggest a constant packing density of both receptors on the cell membrane. (B) Distribution of the estimated intermolecular separations of IL2R
and IL15R
within each individual domain for all images analyzed.
