Table 1. Immunogold densities, EAAT antibodies, type I hair cell and calyx ending.

	EAAT4		EAAT5
	Sample length, µm	Particle density per µm	Sample length, µm	Particle density per µm
Hair-cell membrane	45.1	0.24±0.059	62.3	0.88±0.058
Calyx inner membrane	45.1	0.22±0.060	62.3	0.91±0.29
Calyx outer membrane	64.1	0.11±0.026	51.9	0.038±0.017
Hair-cell cytoplasm	11753*	0.004±0.0005	9385*	0.002±.0007
Calyx cytoplasm	19370*	0.001±0.0003	17537*	0.001±0.0004

Sample lengths, total of five sections for each transporter. Particle density ± SE is based on a regression passing through zero between the sample length and the number of particles for each of the five samples.

^*For the cytoplasm samples, length is multiplied by 0.05 µm to get the sample area.
