  • Product name

    Anti-PADI2 / PAD2 antibody
    See all PADI2 / PAD2 primary antibodies
  • Description

    Rabbit polyclonal to PADI2 / PAD2
  • Host species

    Rabbit
  • Specificity

    ab16478 recognises a specific 75kDa band corresponding to PADI2, which is specifically blocked using the immunizing peptide in human colon, skeletal muscle and kidney lysates. There is a non-specific 18kDa band present in skeletal muscle lysates, which is attributed to cross-reactivity of the PADI2 antibody

  • General notes

    The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

    One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

      Predicted band size: 76 kDa
      Observed band size: 75 kDa
      why is the actual band size different from the predicted?
      Additional bands at: 34 kDa. We are unsure as to the identity of these extra bands.


      Exposure time: 20 minutes


      This blot was produced using a 10% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 5% Bovine Serum Albumin before being incubated with ab16478 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution. The 75-kDa band observed is consistent with what has been described in the literature (PMID:18668562; 20668670; 16723463).

The cells were PFA fixed (10 min), permabilised in 0.1% PBS-Tween (20 min) and incubated with the antibody (ab16478, 5µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue).

    Question

    Sehr geehrte Damen und Herren,

    habe den Antikörper anti-PAD2 (ab16478) im Western Blott eingesetzt und war etwas verwundert weil der Antikörper sehr spezifisch eine Bande bei ca. 75 kDa erkennt (im Kontroll Lysat Hek293 cells). Im Daten Sheet steht drin, dass eigentlich eine Bande von 45 kDa erkannt werden soll. Mir ist auch der kleine Vermerk aufgefallen, in dem steht das die Größe von PAD2 noch nicht geklärt ist. In der Literatur findet man aber eigentlich nur die Info dass PAD2 75 kDa groß ist.

    Meine Frage: Wie kann das denn sein dass der Antikörper das kleinere erkennen soll? Bzw. gibt es einen Literaturnachweis für die kleinere Version? Die im Sheet angegebene ist nicht sehr befriedigend.

    Vielen Dank schon im Vorraus
    und freundliche Grüße

    Asked on Jun 20 2012

    Answer

    Vielen Dank für Ihre Email.

    Leider weiss ich auch nicht genau, was der Unterschied zwischen diesen beiden Banden ist. In UniProt hat es zwei Sequenzen - die annotierte lange Form (http://www.uniprot.org/uniprot/Q9Y2J8) und die noch un- annotierte kurze Form (http://www.uniprot.org/uniprot/Q96DA7).

    Da Sie die HEK293 Zellen benutzen, und wir Nierenlysat benutzt haben, kann ich Ihnen vorschlagen, ein gratis Röhrchen von Nierenlysat als positive Kontrolle zu senden. Dann könnten Sie gleich die beiden Proben vergleichen.

    Es tut mir leid, Ihnen nicht andersweitig helfen zu können. Es scheint mir, dass die Proteinbiologie von PADI2 noch nicht genau erforscht ist.

    Bitte lassen Sie mich wissen, ob Sie dies akzeptieren können und wollen.
