    Target

    • Relevance

      Mycobacterium tuberculosis is the most common cause of tuberculosis. Primary infection begins with inhalation of 1 to 10 aerosolised bacilli. The pathogenicity of the organism is determined by its ability to escape host immune responses as well as eliciting delayed hypersensitivity. Alveolar macrophages engulf the invading cells but are unable to mount an effective defense. Several virulence factors are responsible for this apparent failure; most notably in the mycobacterial cell wall are the cord factor, lipoarabinomannan, and the 65 kd heat shock protein or HSP65. The emergence of new strains of resistant Mycobacterium tuberculosis has created new interest in clinical diagnosis. Studies have shown immunohistochemical techniques to be superior to conventional special stains. Thus the demonstration of mycobacterial antigens are not only useful in establishing mycobacterial aetiology, but can also be used as an alternative method to the conventional Ziehl-Neelsen method.

    Question

    Our customer is looking for anti-BCG antibody for ICC/IF.

    Her sample is BCG infected human tumor cell line.

    I found that you recommended ab20962 as BCG antibody in scientific support Q2 of ab905.

    https://www.abcam.com/Mycobacterium-tuberculosis-antibody-ab905-support.html

    So I would like to know if it is possible to use mycobacterium tuberculosis antibody instead of BCG antibody.

    Please let me know.

    Question

    I am interested in the product ab905, an anti-mycobacterium tuberculosis antibody. Your website mentions that it is specific to a purified protein derivative. I was wondering whether you would be able to give me more information about this protein i.e what the protein is and the normal location of this protein?

    Answer

    Thank you for contacting us.

    This is a polyclonal antibody that was produced using PPD (Purified Protein Derivative) from M. tuberculosis. PPD is a collection of soluble proteins secreted into the culture medium when M. tuberculosis is grown. Thus, there are multiple to which this antibody was raised and react with. Also, because this is a polyclonal antibody, it will react with multiple epitopes on each of the proteins.

    I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

    Question

    Greetings,   I´m a PhD student in Health Sciences at the University of Minho (Portugal) and I need a biotin conjugated monoclonal antibody for Mycobacterium bovis BCG. I would like to know if you have this antibody and, if so, what product would you recommend me for my research. Could you also inform me about the price and availability of this antibody? You used to have a BCG antibody with the code ab34957, but I can no longer find it. Have you got any option? Thank you for your time and consideration. Best regards,

    Answer

    Thank you for your enquiry. I regret to inform you that the originator of this antibody no longer has sufficient stocks for us to be able to make this product available to our customers. We have therefore been forced to withdraw ab34957 from our product range. I do hope that this does not cause you too much inconvenience. I have conducted a search for you and found some alternative antibodies which may suit your need: - Unlabelled: ab43019 ab36731 ab905 ab20962 - Biotin-conjugated: ab20027 - it has only been tested in IHC-P I hope this helps and if I can assist further, please do not hesitate to contact me.

    Submitted Nov 28 2005

    Question

    We were asked by academic referees from Arthritis and Rheumatism to show that our rabbit anti-humanTrpV1 antibodies were not binding to the synovium non-specifically. We chose an "irrelevant" target for human synovium of a rabbit polyclonal antibody directed against an antigen that we did not expect to see in the synovium. Your ab905 was used at the same concentration as our TrpV1 antibody and bound to more targets than TrpV1 (see pictures). Normally, anti-TB, fails to bind to any cells in the synovium (although we do get mast cell peroxidase staining - which is resistant to methanol:h2O2 blocking). Our group has used other anti-TB antibodies for "irrelevant" controls in the past. In other words, we were expecting to see no staining in the synovium, which would confirm that our anti-TrpV1 staining was due to TrpV1 antigen being present. We still believe that TrpV1 antigen is present in the synovium, however, we do not believe that mycobacterium tuberculosi are hiding in the knee! We believe that ab905 is binding to another target in our immunohistochemistry studies. It can clearly to seen in blood vessels and other non-mast cell types. NB. We did parallel experiments in the inflamed rat synovium. Goat anti-E.coli was our irrelevant antibody (I believe it was ab13627), and it did not bind to non-specific targets. Why do you need to know my motivation for using ab905 in the synovium?

    Asked on Nov 02 2005

    Answer

    Thank you for explaining your details to me. I now understand why you would choose to use a anti-TB antibody on mammalian cells. Following your comprehensive experiments it appears that there is clear reactivity against a human target protein by this antiserum. The positive control that we would recommend is an lung infected with TB. However, unfortunately I do not have details of the species that this would have been tested on. On this occasion this antiserum has not performed as detailed on the datasheet. Therefore I would like to offer you a credit note. Before I can do this please can you e-mail me the date of purchase and the original purchase order number. Please can I encourage you to submit an Abreview of this product by navigating to the product datasheet and clicking on the "Abreviews" tab. I look forward to hearing from you.
