Overview

  • Product nameIonomycin (free acid)
  • Description
    Ca2+ ionophore
  • Biological descriptionPotent, highly selective Ca2+ ionophore. Effective mobile ion carrier for Ca2+, highly specific for divalent cations (Ca > Mg >> Sr = Ba). Useful for studies of Ca2+ transport across biological membranes and increasing intracellular Ca2+ concentrations. Complexes with Ca2+ between pH 7 and 9.5. Absorption max. (280 nm, MeOH): 18,600 M-1cm-1.

  • Storage instructionsStore at -20°C (desiccating conditions).
  • Solubility overviewSoluble in ethanol to 10 mM and in DMSO to 10 mM
  • Handling

    Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 6 months.

    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.

      ab58668 staining ATF3 in A549 cells treated with ionomycin (free acid) (ab120370), by ICC/IF. Increase in ATF3 expression correlates with increased concentration of ionomycin (free acid), as described in literature.
      The cells were incubated at 37°C for 2h in media containing different concentrations of ab120370 (Ionomycin (free acid)) 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 ab58668 (10 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-mouse polyclonal antibody (ab96879) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.

    Thank you for contacting us.

    Product ab120116 (Ionomycin Ca2+ Salt) differs from ab120370 (free acid), as the presence of the Ca2+ makes the compound easier to solubilise (the free acid is soluble in ethanol to 10 mM and in DMSO to 10 mM. The Ca...

    Ich habe den WB-Fragebogen ausgefuellt, ich hoffe Sie koennen mir helfen.

    Vielen Dank für Ihre Anfrage und dafür, dass Sie sich die Zeit genommen haben, unseren Fragebogen auszufüllen.

    Die Bande bei 50 kDa sieht in der Tat unspezifisch aus; dies wäre allerdings ja nicht weiter schlimm, wenn Sie die spezifische Bande ...
