    BAPTA-AM purchased from MCE. Usage Cited in: Oncotarget. 2016 Feb 9;7(6):6711-26.

    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.

    BAPTA-AM purchased from MCE. Usage Cited in: Part Fibre Toxicol. 2018 Oct 19;15(1):39.

    Total proteins of BV2 cells are extracted, and the levels of P2X7, NF-κB, ERK and p38 signaling pathway molecules are analyzed via Western Blot.

    BAPTA-AM is an intracellular calcium chelator.

    IC50 & Target

    calcium chelator[1]

    In Vitro

    The permeable calcium chelator BAPTA/AM is known to prevent 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 10μM 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[1].

    Cell Assay

    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].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.
