BAPTA
Based on 39 publication(s) in Google Scholar
BAPTA is a selective and cell-impermeant chelator for calcium. BAPTA has high selectivity against magnesium and calcium. BAPTA can also inhibit phospholipase C activity independently of their role as Ca2+ chelators.

Calcium[1]
BAPTA is widely used as an intracellular buffer to investigate the effects caused by Ca2+ release from intracellular calcium stores or Ca2+ influx via Ca2+-permeable channels in the plasma membrane[1].
BAPTA can be introduced into cells via methods such as patch-clamp and microinjection[1].
BAPTA inhibits PLC activity in isolated Drosophila melanogaster photoreceptor cells with an IC50 of approximately 8 mM[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
