Figure 5. Uptake of connexin selective fluorescence dye, Lucifer Yellow (LY) to the cardiomyocytes.

Cells were incubated with 1-selective binding and/or incorporation of LY was determined fluorescence in the presence of a connexin hemichannel blocker, 50 µM of Lanthanum which was added 30 min prior to LY. *, p<0.05 vs cells in normoxia; n.s., not statistically significant. N = 4 from 4 independent experiments.
