Table 3.

The durations of the individual immobile (a) and mobile (b) events (observed for each single molecule). P values are for comparing PrP and Thy1 (in terms of the duration of each period of the immobile and mobile states) in the same cell type, and show the results of the Mann-Whitney U-test. The differences in the immobile and mobile durations of PrP and Thy1 among the three cell types were complex, and will not be discussed in this report

a. The durations of immobile states
Cells/molecules	Duration of each immobilaiton event (τ obs) (Mean ± SEM [s])	P for PrP vs. Thy1	Duration of each immobilation event after correction for photobleaching (τ immob) (Mean ± SEM [s])	Number of events (n)
CHO-K1 cells
PrP	0.67 ± 0.053	0.98	1.74 ± 0.36	289
Thy1	0.69 ± 0.090		1.84 ± 0.65	131
1-wk neurons
PrP	0.89 ± 0.076	0.56	4.69 ± 2.20	133
Thy1	0.87 ± 0.19		4.11 ± 4.29	31
2-wk neurons
PrP	0.79 ± 0.12	0.018	2.75 ± 1.43	67
Thy1	0.99 ± 0.14		10.41 ± 15.02	62

b. The durations of mobile states
Cells/molecules	Duration of each mobile event (Mean ± SEM [s])	P for PrP vs. Thy1	Duration of each mobile event after correction for photobleaching (Mean ± SEM [s])	Number of events (n)
CHO-K1 cells
PrP	0.45 ± 0.032	<0.001	0.75 ± 0.091	381
Thy1	0.70 ± 0.053		1.91 ± 0.41	252
1-wk neurons
PrP	0.30 ± 0.026	0.0064	0.41 ± 0.049	158
Thy1	0.46 ± 0.070		0.79 ± 0.21	59
2-wk neurons
PrP	0.28 ± 0.041	<0.001	0.38 ± 0.074	70
Thy1	0.52 ± 0.052		0.99 ± 0.19	97
