Summary of kinetic and fluorescence intensity data.

Kinetic and fluorescence values are provided as the mean +/− SD for all events in a given context. The number of experiments and cells analyzed is indicated. The absolute lifetimes are expressed in seconds (s). The % lifetime and % maximum fluorescence intensity values were calculated as described in the legend of Figure 3C. The % maximum fluorescence intensity of cortactin is provided for events analyzed in cells co-expressing mCherry-LCa and cortactin-eGFP. A two-tailed Student's t-test was used to determine whether data from 2 categories differ in a statistically significantly manner. (*) denotes a statistical difference with a p-value <0.005 and >0.00005 when comparing data in a given category to data for pits lacking virus in the same category. (**) similarly denotes a p-value <0.00005. All values for VSV are significantly different (p<0.005 for % max AP-2 fluorescence; p<0.00005 for all other categories) from those measured for DI-T particles in the same context. ND, not determined.
