  • Function

    GTP-binding protein involved in protein trafficking; regulates endocytic recycling and cytoskeleton remodeling. May modulate vesicle budding and uncoating within the Golgi apparatus. Functions as an allosteric activator of the cholera toxin catalytic subunit, an ADP-ribosyltransferase. Involved in the regulation of dendritic spine development (By similarity). Contributes to the regulation of dendritic branching and filopodia extension.
  • Sequence similarities

    Belongs to the small GTPase superfamily. Arf family.
  • Cellular localization

    Golgi apparatus. Cell membrane. Endosome membrane. Cell membrane. Cell projection > filopodium membrane. Recruited to the cell membrane in association with CYTH2 and ARL4C.

    ab131261 was shown to recognize ARF6 when ARF6 knockout samples were used, along with additional cross-reactive bands. Wild-type and ARF6 knockout samples were subjected to SDS-PAGE. ab131261 and ab8245 (loading control to GAPDH) were diluted 1/1000 and 1/2000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 h at room temperature before imaging.

  • Immunocytochemistry/ Immunofluorescence analysis of HeLa (Human cervix adenocarcinoma epithelial cell) cells labeling ARF6 with purified ab131261 at 1/250 dilution (1.1 µg/ml). Cells were fixed in 100% Methanol. Cells were counterstained with ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) at 1/200 (2.5 µg/ml) dilution. Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) was used as the secondary antibody at 1/1000 (2 µg/ml) dilution. DAPI (blue) was used as nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.

  • Flow Cytometry analysis of HeLa (human cervix adenocarcinoma) cells labeling ARF6 with purified ab131261 at 1/250 dilution(10ug/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor® 488)(ab150077)(1/2000 dilution) was used as the secondary antibody. Rabbit monoclonal IgG (Black)(ab172730) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) were used as the unlabeled control.

Merci pour ce supplément d’informations.

Malheureusement nous n’avons pas d’autre lot en stock pour ab131261 et je crains que si je vous envoie en remplacement le même lot, que vous obtiendrez les mêmes résultats.

Je peux vous proposer ab377581 (www.abcam.com/ab77581) qui est aussi garanti de fonctionner en ICC/IF chez l’humain. Sinon, je peux également vous faire un avoir ou un remboursement.

J’attends votre réponse en ce qui concerne la façon dont vous voulez procéder avec cette affaire.

Je suis désolée d'apprendre que ab131261 ne vous donne pas de bons résultats en ICC.

Notre politique est d'offrir tout d'abord la meilleure assistance technique. Si nous concluons que le produit que vous avez reçu ne fonctionne pas comme mentionné sur sa fiche technique et que ce produit a été commandé sous 120 jours, nous nous ferons un plaisir de vous offrir un remplacement gratuit ou un avoir en compensation.

J'aimerais donc vous offrir quelques suggestions afin d'optimiser vos résultats.

Selon l’information sur “Human Protein Atlas” il semble que ARF6 pourrait être localisé au cytoplasme (http://www.proteinatlas.org/ENSG00000165527).

Avez-vous fait un control négative ou un control secondaire pour confirmer que le marquage est en effet non-spécifique?

Pourriez-vous également me faire savoir le numéro de lot d’ab131261 que vous avez reçu ?

J'espère que ces informations vous aideront. Si nos suggestions ne permettent pas d'améliorer vos résultats, n'hésitez pas à me recontacter pour plus d'assistance.
