  • Solubility overview

    Soluble in DMSO to 25 mM and in ethanol to 100 mM
  • Handling

    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 Ca2+ salt (ab120116), by ICC/IF. Increase in ATF3 expression correlates with increased concentration of ionomycin Ca2+ salt, as described in literature.
    The cells were incubated at 37°C for 2h in media containing different concentrations of ab120116 (ionomycin Ca2+ salt) 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.

Question

Dear Supplier,
I am looking to find out which is the more suitable product for me to be using between https://www.abcam.com/ionomycin-ca2-salt-ab120116.html and https://www.abcam.com/ionomycin-free-acid-ab120370.html . I will be using it in cell culture of human cancer cell lines to induce calcium influx. Any help with choosing the more appropriate product would be greatly appreciated.
Thanks

Answer

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 Ca2+ salt is soluble in DMSO to 25 mM and in ethanol to 100 mM).

Apart from this, it may depend on your specific experimental requirements. Some researches prefer not to use the Ca2+ salt as they prefer not to introduce extra calcium into the system.

I hope this information was helpful. Please do not hesitate to contact us should you require further assistance.

Answer

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 bei 120/140 kDa detektieren würden. Ihr Protokoll sieht absolut in Ordnung aus, und daher macht es mir etwas Sorgen, dass Sie keine positiven Ergebnisse erzielen.

Um der Sache auf den Grund zu gehen, würde ich Sie gerne noch nach einigen Details fragen:

Wie haben Sie die Jurkat-Zellen infiziert (Vpr-/wt/M)? Und wissen Sie, ob diese Infektion den T-Zellrezeptorkomplex aktiviert und damit die Expression von NFAT induziert?

Oder anders gefragt: Haben Sie eine Phorbol 12-myristate 13-acetate (PMA)/Ionomycin-stimulierte Positivkontrolle mitgeführt? Sollte der Antikörper mit dieser Kontrolle auch keine Bande für NFAT ergeben, wäre das der Beweis, dass mit dem Vial etwas nicht stimmt, und ich könnte Ihnen umgehend einen kostenlosen Ersatz zusenden. Wir haben zum einen PMA und Ionomycin in unserem Katalog, falls Sie Ihre Zellen selbst stimulieren möchten (ab120297, ab120116, ab120370), oder wir haben Lysate stimulierter Zellen wie zum Beispiel ab14850 oder ab14843 verfügbar.
