Calcium Calibration Buffer Kit
This kit provides buffers for generating a range of accurate calcium concentrations for the calibration of fluorescent Ca2+ indicators.
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.
Fluo-4, pentapotassium salt
Fluo-4, pentapotassium is membrane-impermeant calcium indicator. It can be loaded into cells via microinjection or scrape loading.
Fura-2, AM Ester
Fura-2, AM ester is a ratiometric calcium indicator that is membrane-permeant and can thus be loaded into cells via incubation.
Pluronic® F-127 20% Solution in DMSO
Ready-to-use solution of Pluronic® F-127, a nonionic detergent useful for solubilizing hydrophobic dye molecules such as AM esters of calcium indicator dyes to facilitate cell loading.
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.
