Product nameCalmidazolium chloride, Calmodulin inhibitor
- R 24571
Biological descriptionCalmodulin inhibitor (IC50 = 10 nM). Elevates intracellular calcium, independent of calmodulin inhibition. Additionally inhibits adenylyl cylase activity.
Chemical name3-[Bis(4-chlorophenyl)methyl]-1-[2-(2,4-dichlorophenyl)-2-[(2,4-dichlorophenyl)methoxy)ethyl]-1H-imidazolium chloride
Storage instructionsStore at -20°C. The product can be stored for up to 12 months.
Solubility overviewSoluble in ethanol to 100 mM and in DMSO to 100 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

ab48394 staining LC3B (LC3-II) in HeLa cells treated with calmidazolium chloride (ab120658), by ICC/IF. Increase of LC3B (LC3-II) expression correlates with increased concentration of calmidazolium chloride, as described in literature.
The cells were incubated at 37°C for 6h in media containing different concentrations of ab120658 (calmidazolium chloride) in DMSO, fixed with 4% formaldehyde for 10 minutes at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab48394 (1 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 anti-rabbit polyclonal antibody (ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.
