    BAPTA-AM purchased from MedChemExpress. Usage Cited in: Cell Stem Cell. 2022 Oct 12;S1934-5909(22)00417-9.  [Abstract]

    When HBMEC cells are pre-treated with BAPTA-AM (for 5, 15, 30, 60, 90 min), histamine-induced rapid activation of NF-kB signaling is significantly inhibited.

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

    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 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.

    Description

    BAPTA-AM is a well-known membrane permeable Ca2+ chelator. BAPTA-AM inhibits hERG channels, hKv1.3 and hKv1.5 channels in HEK 293 cells with IC50s of 1.3 μM, 1.45 μM and 1.23 μM, respectively[1].

    IC50 & Target

    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]

    In Vitro

    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].

    Cell Assay
    [1]

    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].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
