The Uses of BAPTA, TETRASODIUM SALT
BAPTA, Tetrasodium Salt is a selective calcium chelator with 105-fold greater affinity for Ca2+ than for Mg2+. This product is a high quality and sensitive compound for calcium signaling studies, investigation of signal transduction and apoptotic cascades, and neuroscience research.
The Uses of BAPTA, TETRASODIUM SALT
Suitable as Ca2+-indicator (fluorescence suppressed by Ca2+). Chelator with a greater selectivity for calcium compared to magnesium.
What are the applications of Application
BAPTA, Tetrasodium Salt is a high quality and sensitive compound for calcium signaling studies
General Description
Ca2+-chelator exhibiting a 105-fold greater affinity for Ca2+ (110 nM) than for Mg2+. After BAPTA complexes with Ca2+, the UV spectrum shifts from 254 to 279 nm at pH >6.0. Useful for spectrophotometric monitoring of extracellular Ca2+ levels, especially transient phenomena, because of its insensitivity to pH. Has been used for the measurement and control of Ca2+ levels in eggs, chromaffin cells, muscle cells, retinal cells, and pancreatic cells. In conjunction with certain formazan dyes, BAPTA can be used in a colorimetric assay for Mg2+. Has neuroprotective effects in vitro against excitotoxic damage and spontaneous recurrent seizures, such as epilepsy.
