Quantitative Analysis of Caveolin Distribution in Exocytic Vesicles from MDCK Cells

		cav-1		cav-2		cav-1/cav-2
HA
10.0 ± 0.9		11.0 ± 0.8		0.5 ± 0.2		19 ± 4
VSV-G
3.8 ± 0.4		6.9 ± 0.7		4.0 ± 0.6		1.6 ± 0.2

The table shows one representative experiment. Routinely, gold label on 40 HA and 40 VSV-G–positive vesicles was quantitated. The number of gold particles counted per vesicle is shown. The ratio of label for caveolin-1 and -2 was calculated for each individual vesicle and is listed under cav-1/cav-2. Standard errors are given.
