  • General notes

    The antibody consists of purified antibody covalently coupled with the N-Hydroxysuccinimide ester of biotin under mild conditions to give a high degree of substitution.

    Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.

    Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.

    We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.

    In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.

    We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.

    Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.

    Please check that this product meets your needs before purchasing.

    • Target

    • Relevance

      Escherichia coli (E. coli) are Gram negative enteric bacteria that live in the human gut. Its presence in nature is an indication of human feacal pollution. E. coli also causes human disease such as urinary tract infections and neonatal meningitis. Infection with particular enterotoxigenic strains can lead to life threatening intestinal diseases. E. coli are distinguished immunologically by serotyping based on three types of antigen: the somatic or O antigen which corresponds to terminal sugars on the cell surface lipopolysaccharide, the capsular or K antigens and the flagellar or H antigens.

    Question

    Thank you for your response! Very helpful.

    I think I’ll have to test for enterobacteriaceae cross-reactivity myself.

    Best regards

    Answer

    I'm glad you found the information of help.

    If you do test any of these antibodies we would be very interested to hear of the results, regardless of if they are positive or not. We like to encourage all of our customers to submit an Abreview via the online product datasheet with any data they collect with our antibodies. As a reward for doing this, each Abreview earns Abpoints that can be used for discounts on future purchases or rewards such as Amazon.com gift certificates.

    To find out more about our Abreview system, please see the following link:

    If you let me know which antibody in particular you are interested in using I may be able to provide you with a testing discount code. More information on this scheme can be found form the following link:

    I hope this information has been of help. If you have any further questions, please do not hesitate to ask.

    Answer

    Thank you for contacting us and your interest in our products.

    I can now share some more information relating to the antibodies we have directed towards E. coli (O and K). We have two different antibodies directed against this bacterium, with different conjugation available:

    ab31499, unlabelled(ab33604, FITC; ab33837, HRP; ab33839, Biotin conjugated of same antibody preparation as ab31499)

    The immunogen for these antibodies is a mixture of the following E. coli strains: O157:H7, O20, O125, O55, O111 & K12. The mixture of these strains was of intact plus lysed bacteria which had not been denatured in any way. All E. coli have many surface and internal antigens in common and this antibody recognizes this large mixture and therefore reacts with most, if not all, E. coli. Theseantibodies have been tested against the strains listed above but have not been cross-absorbed and may react with related Enterobacteriaceae. These potential cross-reacting strains have not been identified.

    ab20765, ab20856 and ab21110 are Biotin, FITC and HRP conjugates of the same antibody.

    These antibodies have been raised against a mixture of E. coli serotypes.These antibodies have been tested for reactivity against the immunogen strains of E.coli but again they have not been absorbed and will most likely cross react withother related Enterobacteriaceae.



    I am sorry that in this case I was not able to be of more help. If you have any further questions, please do not hesitate to contact us again.
