    [Abstract] Cyclic adenosine monophosphate (cAMP) is an intracellular signaling messenger derived from the catalytic conversion of ATP, and is a major product of activated Gs protein-coupled receptors. Conversely, formation of cAMP is inhibited by Gi protein-coupled receptors. This protocol has been optimized for the detection of ...
    Measurement of Free Cytosolic Calcium Concentration ([Ca2+]i) in Single CHO-K1 Cells
    Authors:  Manuel D. Gahete, Raúl M. Luque and Justo P. Castaño, date: 11/20/2012, view: 5895, Q&A: 0
    [Abstract] This is a protocol to analyze the functional response of single CHO-K1 cells to a given treatment in terms of changes in free cytosolic calcium concentration ([Ca2+]i). This is possible by using the Ca2+ indicator dye Fura-2 AM, a polyamino carboxylic acid that binds to free intracellular calcium and is excited at 340 nm and 380 nm. The ratio of ...
