Soluble in water.


BAPTA tetrasodium salt hydrateis a high quality and sensitive compound for calcium signaling studies(investigation of signal transduction and apoptotic cascades, and neuroscience research). BAPTA, Tetrasodium Salt is useful for spectrophotometric monitoring of extracellular Ca2+ levels, with very little sensitivity to pH. Has also been used for the measurement and control of Ca2+ levels in eggs, chromaffin cells, muscle cells, retinal cells, and pancreatic cells. BAPTA-Na4 is a fluorescent compound utilized to determine free Ca2+ by performing fluorescence emission scans at an excitation wavelength of 299 nm and measuring the emission wavelength at 360 nm.


Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents, heat.
