ターゲット情報

  • 関連性

    Human IgG consists of four subclasses (1-4) that can be recognised by antigen differences in their heavy chains. Each subclass has different biological and physiochemical properties. The IgG subclass may be preferentially produced in response to different antigens. The Fab fragment (fragment antigen binding) is the antigen region of the IgG molecule. It is composed of one constant and one variable domain of each of the heavy and the light chain.

    Question

    Has product ab771 ever been tested for blocking exposed IgG fab fragment? Is this antibody specific for IgG fab over fc?

    Asked on Feb 12 2013

    Answer

    We have not performed the blocking assay, but the specificity of this antibody for Fab part of IgG (over Fc) was confirmed by Western blotting using Fab fragments.

    Question

    Whole human IgG adsorbed to a substrate and am looking to determine the amount of adsorbed protein that has the Fab region exposed (as opposed to the total amount of IgG adsorbed). I was planning on using immunofluorescence (preferably) or ELISA to do this, and was wondering if product ab771 would be suitable for this purpose.

    Asked on Jan 09 2013

    Answer

    This product will recognize the Fab fragment of any exposed IgG. However if whole IgG is present and not masked by absorption into the substrate, these too will be recognized. I would recommend performing a co stain with an anti- IgG Fc specific antibody to determine whether the signal seen by ab771 is from Fabs or whole IgG. We offer a Chicken polyclonal to Human + Mouse + Rat IgG Fc fragment (ab15866) which you would be able to use as a co-stain with ab771. As this product is also against mouse Fc I would recommend sequential staining first with ab15866 followed by ab771.

    Asked on Mar 15 2005

    Answer

    Thank you for your enquiry. For Western blotting, I would recommend using ab771 at a dilution of 1:1000 and optimizing based upon results. At the bottom of the online datasheet for ab771 there is a list of compatible secondary antibodies which can be used. One suggestion is ab6728 - Rabbit polyclonal to Mouse IgG H and L (HRP). If you are having problems with high background, you may want to try blocking with 3% BSA, increase the number of washes, and decreasing the concentration of primary antibody as well as the incubation period. Please contact us again if you have any additional questions.

    Abcam community

    Verified customer

    Asked on Feb 11 2004

    Answer

    The originator of these two antibodies has informed me that the anti Fab fragment antibody is better (IgG receptors bind IgG via Fc so it may be occupied). The Fc fragment is not good for IgM bound to the B-cell surface, but is great for soluble IgM.
