  • (A) Representative fluorescent images of co-localization of NLRP3 and mitochondria in NP cells as described in Figure 6C. Red and green fluorescence indicated NLRP3 and mitochondria signals, respectively. Cell nuclei are stained by DAPI. Representative fluorescent images of caspase-1 activity (B) in NP cells.

  • BAPTA/AM and STO609 pretreatments did not inhibit BAM15-induced AMPK activation in A10 cells. A10 cells were treated with BAM15 (5 μmol/L, 5min) after BAPTA-AM (20 μmol/L, 1h) and STO-609 (50 μmol/L, 1 h) pretreatments. **P<0.01 vs DMSO (control).

  • Formation of the AnxA2 complex in MBMECs was evaluated by immunoprecipitation and Western blot analysis after cryptococcal exposure. Endothelial cells were treated with PP2, BAPTA-AM, or DMSO (control) for 1 h before infection with cryptococcal cells and then rinsed twice with warm PBS. Lysates of infected or noninfected endothelial cells were preincubated with anti-AnxA2 Ab, and bound proteins were then blotted with anti-S100A10 Ab.

  • Calcium chelator (BAPTA-AM) reduces HBV replication in CD36OE of HepG2.2.15 and HepAD38 cells. BAPTA-AM or vehicle controls (DMSO) were added to the CD36OE of HepG2.2.15 and HepAD38 cells for 96 h, and HBV DNA were extracted and detected by Real-time PCR (n = 4). Cytosolic Ca2+ was measured after treatment for 48 h using flow cytometry (n = 3).

  • A549 lung cancer cells were serum starved prior to treatment with TGF-β1 (10 ng/mL) or control for 12h in the presence or absence of BAPTA-AM (100μM). Protein expressions of Smad2/3, PSmad2 and P-Smad2 were detected by western blotting. (Values are shown as the mean ± SD. n=3, a representative experiment is shown; ‘*’means P<0.05)

Purity & Quality Control

Biological Activity

Description BAPTA-AM is a selective, membrane-permeable calcium chelator.
In vitro

BAPTA-AM, as an intracellular calcium chelator, induces delayed necrosis by lipoxygenase-mediated free radicals in mouse cortical cultures. [1] BAPTA-AM exerts an open channel blocking effect on hERG, hKv1.3 and hKv1.5 channels with IC50 of 1.3, 1.45 and 1.23 μM in HEK 293 cells. [2]

Effects of BAPTA-AM (20 µM, 30 min) on SKF83959 (30 µM, 10 min)-induced ERK1/2 phosphorylation. 

In vivo BAPTA-AM abolishes the UDCA- and TUDCA-induced increases in Ca2+ levels or Ca2+-Dependent PKC-α phosphorylation, and neutralizes the cytoprotective effects of UDCA and TUDCA on the vagotomy-induced damage of the biliary tree in the BDL rats. [3]

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
