    This kit provides buffers for generating a range of accurate calcium concentrations for the calibration of fluorescent Ca2+ indicators.

    Probenecid, Sodium Salt, Water Soluble

    Probenecid is commonly used to inhibit organic-anion transporters located in the cell membrane. Such transporters can extrude dyes and indicators and thus contribute to low signal or high background in assays due to poor cellular retention of dyes.

    Membrane-permeant form of Fluo-4 calcium indicator.

    Fluo-3, AM Ester

    Membrane-permeant AM ester form of Fluo-3 that can be loaded into cells via incubation. Because of the relatively low water solubility of the AM ester, Pluronic F-127, a mild detergent, is often used as a dispersing agent to facilitate dye loading.

    Ionomycin is commonly used to modify intracellular calcium concentrations and to calibrate fluorescent calcium indicators. It is also known for its antiproliferative effects.
