Table 1. RIs of mitochondria with different ranges of the half widths.

Range of half width [nm]a	Nb	Half width [nm]c	Max.ΔOPL[nm]d	RIe
710–770	10	735 ± 2	32 ± 7	1.41 ± 0.01
700–780	15	734 ± 3	31 ± 7	1.41 ± 0.01
690–790	20	736 ± 3	30 ± 7	1.41 ± 0.01
680–800	22	741 ± 3	30 ± 7	1.41 ± 0.01

^a: Half widths were obtained as described in section 3.2.

^b: The number of analyzed mitochondria.

^c,d,e: The data were expressed as the mean ± SD.

^e: The RIs were calculated with Eq. (3) by assuming the RI of silica beads was 1.43.
