    • Relevance
      Mycobacterium is a genus of actinobacteria, given its own family, the Mycobacteriaceae. It includes many pathogens known to cause serious diseases in mammals, including tuberculosis and leprosy. Mycobacteria can be classified into several major groups for purpose of diagnosis and treatment: M. tuberculosis complex which can cause tuberculosis: M. tuberculosis, M. bovis, M. africanum, and M. micoti. M. leprae which causes Hansen's disease or leprosy. Nontuberculous mycobacteria (NTM) are all the other mycobacteria which can cause pulmonary disease resembling tuberculosis, lymphadenitis, skin disease, or disseminated disease.

    Thank you for your enquiry. I can confirm that the immunogen for ab20832 Mycobacterium antibody was a cell wall extract of M. tuberculosis. The exact proteins in the immunogen were not characterized. This antibody reacts primarily against lipoarabinomannan (LAM), but also shows reactivity to other mycobacterium proteins. This is a polyclonal antibody and therefore recognizes many epitopes on several proteins. I am sorry the epitopes have not been mapped. Unfortunately, we are not aware of a published reference using this antibody. Any we are aware of would be listed on the datasheet. I hope this information is helpful to you. Should you have any further questions, please do not hesitate to contact us.

    Thank you for contacting us.

    The concnetration has not been determined for this antibody as it is provided as whole antiserum. It thus contains other proteins and serum IgGs that would interfere with a protein assay for the specific antibody.

    A rough estimate for the concnentraion of the specific IgG in serum in general is max. 1 mg/ml (10% of the total IgG conc) at best.

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

    The Anti-Mycobacterium antibody (ab20832) has as yet only been used in ELISAs. This does not mean that it would not work in other applications, simply that we have not tested it ourselves and would therefore not be able to guarantee its performance.

    However, if you would like to purchase ab20832 and use it with your samples measured by flow cytometry, we can offer you a testing discount. This offer means that if you purchase ab20832 as normal, test the antibody and let us know of the results through an Abreview (no matter whether positive or negative) you would be eligible for a free primary antibody of your choice from our catalogue (or the equivalent price of ab20832 off any product). More information on this offer can be found here:


    Please note that the antibody to be tested must be purchased, tested, the Abreview submitted and the free product claimed within a 4 month period.

    If you would be interested in participating in this scheme please do let me know as a discount code needs to be issued prior to the purchase of ab20832.

    I have noticed that you tend to reply using the website contact form. Please feel free to reply directly to my emails, this means they will more likely be directed to me and I will know what the case is about.
