Optical readout of network connectivity in HeLa cells loaded with Vf2.1.Cl. (A) HeLa parental cells. (B, C, D) Transiently transfected HeLa cells showing increasing amounts of interconnectivity provided by hCx26–CFP gap junction channels; images of CFP fluorescence emission from chimerical proteins are shown at left, the corresponding Vf2.1.Cl relative amplitude data at right (integration cycles N = 25); scale bars, 25 μm.
