The channels in the junctions of various mammalian cell types--primary cultures and lines--were probed with a series of linear fluorescent amino acid and peptide molecules of different size and charge. Permeability is limited by probe size and electronegativity, these two factors apparently being related reciprocally. In respect to both factors, mammalian… CONTINUE READING
