Comparison of diffusion coefficients of class I MHC molecules on normal MEL and α-spectrin-deficient MEL measured by FRAP and SPT

	FRAP (μm2/s) Fab		FRAP (μm2/s) Bead		SPT (μm2/s)
	Mean*	±c†	n‡	Mean*	±c†	n‡	Dmacro§	Dmicro*	±c†	n‡
Normal	0.06	0.02	25	0.02	0.01	20	0.004	0.007	0.002	262
Mutant	0.07	0.02	25	0.03	0.01	20	0.007	0.02	0.005	171

^*This is geometric mean.

^†This is the 95% confidence interval from geometric mean.

^‡Experiment or particle number.

^§Because D_macro was calculated from ensemble averaging, there was no SD.
