General description
La référence F3165 est purifiée par affinité sur une résine avec de la protéine A : elle contient donc non seulement l'anticorps anti-FLAG M2 mais aussi de petites quantités d'IgG native de souris, ce qui augmente sa sensibilité dans la plupart des applications.
Méthode de purification - Protéine A
Immunogen
Application
- Immunoblotting/Immunotransfert
- Immunoprécipitation
- Immunocytochimie
- Immunofluorescence
- Dosages ELISA
- Dosages immunoenzymatiques
- Immunoprécipitation de la chromatine
- Microscopie électronique
- Cytométrie en flux
- Tests supershift

Preparation Note
Remarque : Au fil du temps, de petites quantités d'anticorps purifiés peuvent précipiter à partir de la solution en raison d'interactions hydrophobes intermoléculaires. Si un précipité est observé dans ce produit, centrifuger brièvement le flacon pour obtenir un culot contenant le précipité. Prélever le volume de solution d'anticorps souhaité dans le surnageant limpide avant utilisation. Cela ne devrait pas altérer la performance de l'anticorps purifié dans les applications de western blotting ou d'immunoprécipitation.

Is there a recommended dilution for capture (sandwich) based ELISA?
1 answer-
Monoclonal ANTI-FLAG® M2 may be used in EIA procedures. Typically, a fusion protein containing a FLAG® peptide sequence is directly adsorbed (or otherwise presented) within the wells of a multiwell polystyrene plate. The Monoclonal ANTI-FLAG® M2 antibody may be diluted up to 1:50,000 for subsequent incubation within the plate wells. Detection may be accomplished using Anti-Mouse IgG-Peroxidase (Cat. No. A9044) or equivalent, diluted 1:10,000, followed by an appropriate substrate for visualization.
Dilutions for use as the capture antibody in an ELISA have not been evaluated. We would recommend that the end-user optimize the protocol following the recommendations found here:

What is the difference between F1804 and F3165 product?
1 answer-
Product F1804 and F3165 are both Monoclonal ANTI-FLAG M2 antibodies produced in mouse Clone M2, with the same starting material. The distinction between the products lies in their purification methods. F3165 is immunoglobulin purified, while F1804 is immunogen affinity purified. F1804, being more purified, is expected to exhibit reduced background and less non-specific staining compared to F3165. Both products are suitable for western blotting, immunofluorescence, and immunoprecipitation.

What type of light chain is present on the FLAG M2 antibody?
1 answer-
Test has not been conducted to determine whether the light chains of the antibody F3165, Monoclonal ANTI-FLAG® M2 antibody produced in mouse, are kappa or lambda. However, based on customer feedback, it appears that the M2 monoclonal antibody has lambda light chains and not kappa. A probe with anti-kappa did not yield a signal, while anti-lambda produced a good signal.
