Application Abreviews Notes
ChIP Use at an assay dependent concentration.
WB 1/500 - 1/2000. Detects a band of approximately 67 kDa (predicted molecular weight: 57 kDa). Splice variants exist for this protein that may result in the detection of lower molecular weight bands.
IHC-P Use a concentration of 2 - 5 µg/ml.
ICC/IF Use a concentration of 1 µg/ml.
ELISA 1/3000 - 1/10000.
EMSA Use at an assay dependent concentration. PubMed: 21609478

    Lane 1 : HeLa Nuclear extract
    Lane 2 : HeLa Whole Cell lysate

    All lanes : IRDyeTM700 labelled goat-a-rabbit IgG at 1/2500 dilution

  • Purified anti-NRF1 antibody (ab34682) was used at 5µg/ml to detect NRF1 in human testis. Nuclear staining in lymphocytes can be observed.
  • ICC/IF image of ab34682 stained HeLa cells. The cells were 4% PFA 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 (ab34682, 1µg/ml) overnight at +4°C. 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) 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 Nachricht! Es freut mich zu hören, dass das neue Röhrchen ein gutes Signal gibt auf dem Mausgewebe.

Es ist erstaunlich, dass das Signal auf dem Muskel nicht mehr da ist. In der Tat ist das Protein vielleicht auch degradiert? Haben Sie ein frisches Lysat, welches Sie testen könnten? Ist das Muskellysat auch von der Maus?

Ich hoffe, dass beim zweiten Versuch alles gut läuft. Ich würde mich über eine kurze Rückmeldung wieder freuen.

Vielen Dank für Ihre Kooperation! Ich freue mich wieder von Ihnen zu hören!

Vielen Dank für Ihre Antwort.

Es tut mir leid, dass der ab34682 kein Signal mehr gibt. Leider kann ich mir nicht erklären, wieso dies so ist. Wir werden Ihnen gerne einen Ersatzantikörper senden. Könnten Sie bitte hierzu die Eckdaten des Protokolls mit dem angehängten Fragebogen eingeben (für unsereQualitätskontrolle), inklusive des Bestelldatums oder der Bestellnummer? Vielen Dank für Ihre Mitarbeit.

Bitte bestätigen Sie mir auch, ob Sie gerne ein Ersatzröhrchen von ab34682 hätten, oder lieber einen alternativen Antikörper.

Ich freue mich wieder von Ihnen zu hören.
