BAPTA tetrasodium salt ≥95% (by TLC) ion chelator, for calcium determination

BAPTA tetrasodium salt

BAPTA and its derivatives are calcium chelators that are commonly used to form calcium buffers with well-defined calcium concentrations. By injecting the chelators into cells or by incubating cells with the AM ester form of the chelators, one can control the cytosolic calcium concentration, an important means to study the roles of calcium.

Kd (no Mg2 ): 0.59 uM, Kd (1 mM Mg2 ): 0.70 uM
Cell permeability: Membrane impermeant
White solid soluble in water
Store at 4°C

Key advantages of these calcium chelators include relative insensitivity toward intracellular pH change and fast release of calcium. Biotium offers several BAPTA chelators with calcium dissociation constants covering the biologically significant range from 10-7 to 10-2 M.
