    • ICC/IF image of ab3125 stained PC12 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 (ab3125, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse 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.

    • ab3125 staining p75 NGF Receptor in Human cholinergic neurons by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded tissue sections). The sections were fixed in formalin and subjected to heat-mediated antigen retrieval in sodium citrate buffer prior to blocking with 2.5% serum for 1 hour 30 minutes at 21°C. The primary antibody was diluted 1/250 in normal horse serum blocking buffer and incubated with the sample for 65 hours at 4°C.

    • ab3125 staining p75 NGF Receptor in human melanoma tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections).
      Tissue was fixed in formaldehyde and a heat mediated antigen retrieval step was performed using Tris EDTA pH 9.0. Samples were then permeabilized using 0.25% Triton X-100, blocked for 1 hour at room temperature and then incubated with ab3125 at a 1/100 dilution for 18 hours at 4°C. The secondary used was an Alexa-Fluor 594 (red) conjugated donkey anti-mouse polyclonal used at a 1/100 dilution. (Green) tumor cells, (blue) DAPI.

    We do not have any free samples or small samples of any of our antibodies but both ab12228 and ab3125 will be covered by our guarantee for one year if you plan on using them for flow cytometry with samples that are one of the species listed on the datasheets. (Human, ferret, and monkey are listed on the ab3125 datasheet and human, mouse, rat and several others on the ab12228 datasheet).

    Note that metallothionein is cytoplasmic, so you will not be able to sort live cells. Antibody ab3125 anti-p75 NGF Receptor, on the other hand, recognizes an extracellular epitope, so you should be able to sort live cells.

    Merci pour votre émail. Je suis désolée que nous pouvons par regarder les images du coup. Nous sommes en Angleterre, et je pense que ça va devenir compliqué pour envoyer les lames.

    Je vais chercher pour trouver des images de mon coté et je vous tiens au courant. Est-ce que en attendant, vous pouvez me confirmerles pointssuivants:

    1.)que ces bien des tissus d'origine humaine que vous avez marqué? Ou c'est des tissus d'origine de souris?

    2.) C'est quoi comme sérum que vous avez utilisé pour bloquer les lames?

    3.) A votre avis, le problème vient de quel réactif?

    Je me réjouis de votre réponse. Veuillez s'il vous plait aussi me confirmer comment vous souhaitez procéder.

    Le tissu cérébral humain est en effet un tissu de choix pour l'expression de TrkA, NGF et le récepteur p75 NGF. Avez-vous reçu ces 3 anticorps en même temps (même colis de livraison)?

    Merci de nous avoir contactés. Je suis désolé d'apprendre que vous avez eu des difficultés à obtenir de bons résultats avec ab3125, ab6199, ab37837 en IHC-P. 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 6 mois, nous nous ferons un plaisir de vous offrir un remplacement gratuit ou un avoir. J'aimerais donc vous offrir quelques suggestions afin d'optimiser vos résultats. - Pour les 3 anticorps je recommanderais une incubation sur la nuit à 4°C (ou même à température ambiante) en prenant soin que les échantillons ne soient pas sujet à évaporation. Pour les dilutions des anticorps primaires, se reporter aux fiches techniques. - Pour les 3 anticorps je recommanderais également un démasquage de l'antigène à haute température en utilisant du tampon Tris EDTA pH 9,0. Pourriez-vous me communiquer quelques détails concernant la préparation des échantillons (agent et temps de fixation)? Les anticorps secondaires sont-il compatibles? Sont-ils bons? J'espère que ces informations vous aideront. Si les suggestions ne permettent pas d'améliorer vos résultats, n'hésitez pas à me recontacter pour plus d'assistance.
