  • Function

    Involved in antiviral defense. May impair virus budding by disrupting lipid rafts at the plasma membrane, a feature which is essential for the budding process of many viruses. Acts through binding with and inactivating FPPS, an enzyme involved in synthesis of cholesterol, farnesylated and geranylated proteins, ubiquinones dolichol and heme. Plays a major role in the cell antiviral state induced by type I and type II interferon. Displays antiviral effect against HIV-1 virus, hepatitis C virus, human cytomegalovirus, and aphaviruses, but not vesiculovirus.
  • Sequence similarities

    Belongs to the RSAD2 family.
  • Cellular localization

    Endoplasmic reticulum membrane. Golgi apparatus. Probably associates with the cytosolic side of the endoplasmic reticulum. Infection with human cytomegalovirus (HCMV) causes relocation to the Golgi apparatus and to cytoplasmic vacuoles which also contain HCMV proteins glycoprotein B and pp28.

  • ICC/IF image of ab78364 stained U87-MG cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab73864, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Vielen Dank für Ihre Anfrage.

Es freut mich zu hören, dass ab73864 im Western blot gut funktioniert.

Wir haben diesen Antikörper bisher noch nicht in der Immunhistochemie (IHC) getestet, und wissen daher leider nicht, ob bzw. wie er funktionieren könnte.

Wenn wir Antikörper für die IHC testen, probieren wir in der Regel zwei verschiedene Konzentrationen (1 und 5 µg/ml) und jeweils zwei unterschiedliche Probenpräparationen aus. Letztere sind zum Beispiel entweder Paraformaldehyd- (PFA) oder Aceton-fixierte Gefrierschnitte, oder beispielsweise mit Zitratpuffer pH6 oder Tris/EDTA-Puffer pH9 demaskierte Paraffinschnitte. Je nach Ergebnis können die Konzentration und die Versuchsbedingungen dann noch weiter optimiert werden. Für weitere Details habe ich Ihnen unsere Protokolle angehangen, die Sie auch auf unserer Webseite finden (https://www.abcam.com/index.html?pageconfig=popular_protocols).

Falls Sie mit diesem Antikörper gute Ergebnisse in der IHC erzielen, würden wir uns über eine Rückmeldung mittels eines Abreviews freuen. Das Abreview-System erlaubt es unseren Kunden, Rezensionen unserer Produkte zu veröffentlichen und dafür Punkte zu erhalten. Diese “Abpoints” können gegen Rabatte beim Kauf weiterer Produkte oder Geschenkgutscheine wie z.B. Amazon.com-Gutscheine eingetauscht werden. Unter der folgenden URL können Sie mehr über unser Abreview-System zu erfahren: https://www.abcam.com/abreviews

Und noch ein Tipp: Falls Sie den Antikörperwieder neu bestellen müssen, geben Sie uns vorher bescheid. Dann können wir Sie nämlich in unser Testprogramm aufnehmen, bei dem Sie einen kostenlosen Antikörper bekommen, wenn Sie uns Ihre Testergebnisse mitteilen. (Leider können wir den entsprechenden Rabattcode nicht nachträglich ausstellen.) Weitere Informationen finden Sie unter: https://www.abcam.com/collaborationdiscount

Ich hoffe, diese Informationen helfen Ihnen weiter, und wünsche Ihnen viel Erfolg für Ihr Projekt. Bitte zögern Sie nicht, sich wieder bei uns zu melden, falls Sie weitere Fragen haben.
