    Target

    • Relevance

      Nitric oxide (NO) is a product of the enzymatic conversion of arginine to citrulline by nitric oxide synthase. NO reacts rapidly with superoxide to form peroxynitrite. At physiological pH and in the presence of transition metals, peroxynitrite undergoes heterolytic cleavage to form hydroxyl anion and nitronium ion, the latter of which nitrates protein tyrosine residues. Thus, the presence of nitrotyrosine on proteins can be used as a marker for peroxynitrite formation in vivo. The presence of nitrotyrosine has been detected in various inflammatory processes including atherosclerotic placques.

    danke für Ihre schnelle Antwort. Angehängt schicke ich Ihnen den Fragebogen. Die Problematik die wir sehen steht auch drinnen beschrieben. Wir hoffen wir können zu einer Lösung unseres Problem kommen.

    Answer

    Vielen Dank für Ihre Anfrage und dafür, dass Sie sich die Zeit genommen haben, unseren Fragebogen auszufüllen.

    Es tut mir leid, dass Sie Probleme mit unserem Antikörper hatten.

    Um Ihr Problem zu lösen, möchte ich die folgenden Vorschläge zu Veränderung Ihres Protokolls machen:

    1. Um die Qualität des Antikörpers zu überprüfen, wäre es hilfreich eine positiv Kontrolle durchzuführen. Als positiv Kontrollen für Mausproben empfehlen wir auf unserem Datenblatt beispielsweise mouse kidney lysate, mouse optic nerve, retina , spinal cord and brain lysates.

    2. Um die Qualität der Proben zu testen würden wir empfehlen eine Ladekontrolle in das Experiment zu integrieren. Dieses würde zusaetzlich zeigen, dass die Proteinproben auf die Membran übertragen werden.

    3. Da die detektierten Banden in den Proben von der Größe mit der schweren und leichten Kette von Antikörpern übereinstimmen, ist zu vermuten das endogene in der Probe enthaltene Antikörper von den verwendeten sekundären Antikörpern erkannt werden. Diese kann durch die Verwendung eines Antikörpers vermieden werden, der nur die native Form des IgG erkennt. Einen solchen können Sie in unserem Katalog finden (Anti-mouse IgG VeriBlot for IP secondary antibody (HRP) (ab131368) ).


    Bitte lassen Sie mich wissen, ob ich Ihnen helfen konnte und zögern Sie nicht, sich wieder bei uns zu melden, falls Sie weitere Fragen haben.

    Question

    We currently don't have nitrated BSA (ab131379) from Abcam. We have a nitrated BSA from Sigma which could not be recognized by ab7048, and I was told the nitration percentage of the product is not very high. We are thinking about getting the nitrated BSA from Abcam. But before I place the order, my supervisor wants some guarantee that nitrated BSA (ab131379) will work with the ab7048 antibody, and if it doesn't, can we have a replacement or reimpurse?

    Read More
    Answer



    There is a western blot on our online datasheet for ab131379 https://www.abcam.com/bovine-serum-albumin-protein-nitrated-ab131379.html illustrating this protein to be detectable by ab110282, another Anti-Nitrotyrosine antibody. So we will guarantee that ab131379 will be a good positive control for western blotting, as long as you follow up with us within 6 months of purchasing the product.

    Question

    Thank you for taking the time to help us out with this antibody. We contacted another lab who is successfully using another one of your antibodies to nitrotyrosine, specifically ab78163. We would be happy to get a refund and place an order for that antibody, or just get that antibody sent to us as a replacement. Whichever route is the easiest is fine with me. Would you like us to send back the remaining nitrotyrosine antibody that isn't working for us?
    The original order number for the ab7048 antibody was **

    Answer

    Thank you for calling Abcam earlier today.

    I am sorry about the issues you have been having with ab7048. Asrequested I am sending you a new vial of the antibody, ab78163and you should receive that tomorrow morning. For your reference, your new order number is **.

    If there is anything else I can help you with, please let me know.

    Question

    I have attached our current protocol for staining HUVEC cells. The secondary antibody I have been using with ab7048 is a donkey anti-mouse Alexa 594. I have confirmed that the secondary antibody works using an independent antibody for actin.

    Read More
    Answer

    Thank you for providing that information.

    Having looked over the protocol you provided, I do not think that there is any advice I could give that would help resolve the issues that you are having. Therefore I would be happy o either replace or refund the cost of the antibody for you.

    Please let me know how you would you like to continue and if you could also provide either the Abcam order number or the PO# used to purchase the antibody, that would be very helpful.

    Question

    Hello,
    We recently purchased the Anti-Nitro tyrosine mouse monoclonal (HM.11) that was listed as ab7048. I can no longer find this catalog number in your system, and I am assuming that ab94883 is the same product. Our problem is that we detect absolutely no staining using this antibody. We are staining the HUVEC cell line, and human endothelial cells collections. Both of these have been fixed (0.75% Formaldehyde OR 4% Paraformaldehyde), frozen and affixed to slides. We purchased this antibody because my PI's previous lab had successful staining on HUVECs with it, and we are using their protocol. When we co-stain with ab8822 (Anti-Von Willebrand Factor (FITC)), we get a beautiful signal from ab8822 and nothing from ab7048. When we stain with ab7048 alone, we likewise get nothing. We have even treated the cells with ROS prior to fixing them to induce a response. We are using Donkey anti-mouse Alexafluor 596 as a secondary antibody. We have confirmed that this secondary antibody is working by using it with a separate primary antibody to actin. Do you have any suggestions to get this antibody to work? Alternatively, we would be happy to trade it in for a different nitro tyrosine antibody if this one is problematic.

    Answer

    Thank you for contacting Abcam.

    I am sorry about the problems you have been having with ab7048, which is still in the catalogue and can be found at the link below:

    https://www.abcam.com/Nitro-tyrosine-antibody-HM-11-ab7048.html



    The antibody is covered under our Abpromise for six months and is guaranteed to work inIHC-P& IHC-Fr. If we cannot resolve the issue you are having with the antibody then I would be happy to either send a replacement antibody or to process a refund.

    To be able to help you further in this matter would you be able to send me the complete protocol that you are using. I know you mentioned that you were getting really good staining with the protocol previously and that it worked for ab8822, but I may be able to make some suggestions. If not, then I will be happy to replace the antibody for you.

    I look forward to your reply and helping to resolve this issue.
