Figure 1From: Molecular targets for the protodynamic action of cis-urocanic acid in human bladder carcinoma cells cis-UCA induces intracellular acidification in 5637 bladder carcinoma cells. 5637 cells were labelled with BCECF prior to treatment with cis-UCA at indicated concentrations in buffer solutions adjusted to pH 7.4 or pH 6.5. After one hour the samples were analysed by flow cytometry for intracellular pH.Back to article page
