  • General notes

    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.

Target

  • Relevance

    Shiga toxins are a family of related toxins with two major groups, Stx1 and Stx2, whose genes are considered to be part of the genome of lambdoid prophages. The most common sources for Shiga toxin are the bacteria S. dysenteriae and the Shigatoxigenic group of Escherichia coli (STEC), which includes serotype O157:H7 and other enterohemorrhagic E. coli (EHEC).

    Question

    Are they using the purified protein or anEHEC O157:H7 lysate? If the later, I would suggest to increase the protein load up to 20 to 30ug per lane to offer the antibody enough target protein.
    - They used lysate and it's hard to get enough sample, he concentrated the protein and applied. Protein sample loaded 15ug/lane and he said he couldn't loading more than that because sampling was difficult.

    How was the transfer verified?
    -It was checked by ponceau staining.

    For a better saturation of the membrane, I would recommend a blocking buffer containing 3% BSA for 2 hours at room temperature. BSA can sometimes give better results than milk. If you are going to switch to BSA, please switch the incubation buffer as well.
    -This is not about non-specific band so the customer thinks it'snot necessary to try BSA blocking

    Could you please confirm the host species of the secondary antibody and the species it reacts against?
    -anti-mouse IgG(HRP)


    They checked DNA level byPCR and this WB is for last confirmation.

    Answer

    Thank you for your reply.


    Indeed, usually the blocking step is connected with the occurrence of side bands. However, changing the blocking agent can significantly increase the signal strength as our lab found out. I have attached a PDF which shows what can happen when you use the same material and protocol except for the blocking agent.


    I hope this information is helpful to you.If the results do not get better, we will certainly replace the product.

    Asked on Mar 14 2012

    Answer

    Thank you for taking time to complete our questionnaire. I am sorry to hear that this antibody is not providing satisfactory results.

    The details provided will enable us to investigate this case and will provide us with vital information for monitoring product quality.

    Having reviewed this case, I would like to offer some suggestions to help optimize the results fromab101839. I would also appreciate if you can confirm some further details:

    Are they using the purified protein or anEHEC O157:H7 lysate? If the later, I would suggest to increase the protein load up to 20 to 30ug per lane to offer the antibody enough target protein.
    How was the transfer verified?
    For a better saturation of the membrane, I would recommend a blocking buffer containing 3% BSA for 2 hours at room temperature. BSA can sometimes give better results than milk. If you are going to switch to BSA, please switch the incubation buffer as well.
    Could you please confirm the host species of the secondary antibody and the species it reacts against?





    Should the suggestions not improve the results, please do let me know.

    In the event that a product is not functioning in the species and applications cited on the product datasheet (and the problem has been reported within 6 months of purchase), we would be pleased to provide a free of charge replacement, credit note, or refund.

    I hope this information is helpful, and I thank you for your cooperation.
