Ca2+ chelator[1]
IC50: 1.3 μM (hERG channel, in HEK 293 cells), 1.45 μM (hKv1.3, in HEK 293 cells), 1.23 μM (hKv1.5, in HEK 293 cells)[1]
BAPTA-AM inhibits neuronal Ca2+-activated K+ channel currents, and up-regulates the decreased cardiac sodium current (INa) density by chelating intracellular Ca2+[1].
BAPTA-AM (BAPTA/AM), an intracellular calcium chelator, induces delayed necrosis by lipoxygenase-mediated free radicals in mouse cortical cultures. BAPTA-AM prevents free radical-mediated toxicity promote apoptosis in non-neuronal cells and produce a beneficial effect in neuronal cells by protecting neurons from ischemic damage. In addition, it has been suggested that BAPTA-AM induces a late, but not early, increase of intracellular calcium in I-IL-60 neoplastic cells. Mixed cortical cell cultures (DIV 13-16) exposed to 10 μM BAPTA-AM for 24- or 48-hr show moderate (45-70%) neuronal injury as evaluated by increased LDH release into the bathing medium after 24-48-hr. Exposure of cortical cultures to 3-10 μM BAPTA-AM for 48-hr evoke dose-dependent neuronal damage[2].

BAPTA-AM purchased from MedChemExpress. Usage Cited in: Oncotarget. 2016 Feb 9;7(6):6711-26. [Abstract]
Under conditions of glucose limitation, BAPTA-AM treatment prevents HBx-induced phosphorylation of AMPK and ACC (A). This inhibitory effect is also observed in HBV-infected HepG2.2.15 cells in a concentration-dependent manner (B), implying that HBx-mediated mitochondrial calcium channels are required for activation of the AMPK pathway under such stressful conditions.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (3.27 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
Neuronal injury is quantitatively estimated by measuring lactate dehydrogenase (LDH) released from damaged cells into the bathing medium 24- or 48-hr after the 10 μM BAPTA/AM treatment. The morphological findings are confirmed by staining with neuron-specific enolase (NSE) antibody and tryphan blue[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
