Single channel permeabilities (×10⁻¹⁰ mm³ min⁻¹) for Alexa dyes through connexin channels

Cx	Alexa 350	Alexa 488	Alexa 594
45.6	3.24 ± 0.24 (7)	0.94 ± 0.12 (6)	0 (6)
43	1.14 ± 0.08 (5)*	2.93 ± 0.02 (4)*†	1.23 ± 0.06 (6)*
45.6–43 N	1.6 ± 0.08 (6)*	1. 6 ± 0.05 (5)*	0.91 ± 0.07 (4)*

Values are mean ±s.e.m. of (AP)_pore (units of 10⁻¹⁰ mm³ min⁻¹). Number of data sets used in calculating permeability shown in parentheses. The (AP)_pore of Cx43 and Cx45.6–43N were significantly different from Cx45.6 when evaluated with a student's t test

^*P < 0.001. The (AP)_pore of Cx43 was significantly different from Cx45.643N when evaluated with a student's t test

^†P < 0.001.
