The following are the results of imaging and analysis of the increase of intracellular Ca2+ concentration in A10 cells, using the CellVoyager, by treatment of ionomycin, a Ca2+ ionophore. | Yokogawa Canada Introduction Changes in intracellular Ca 2+ concentration are an important analysis target in the study of intracellular signal transduction related to physiological phenomenon, such as

MagFRET: The First Genetically Encoded Fluorescent …

Mutagenesis of metal binding site residues allowed further tuning of the metal binding properties, yielding MagFRET variants with K d values for Mg 2+ binding ranging between 0.15 and 15 mM. While also responsive to Ca 2+ in vitro , we show that the Ca 2+ affinities of the MagFRET sensors are sufficiently attenuated that they are not responsive to normal Ca 2+ fluctuations in situ .
