    Question

    Customer has purchased ab422 and needs to know the following information about this antibody: how was the antigen generated? Was cross-linking (such as BSA) involved in generating the peptide? To generate a control, what should the antibody be pre-absorbed with? Any information to help her would be greatly appreciated! Thank you in advance!

    Asked on Dec 15 2003

    Answer

    Antigen: BSA; ab422 is a monoclonal and does not need to be pre-absorbed.

    Question

    Hi I`m using your ab 422. Two questions. Do you know if this antibody could be used in flow cytometry analysis? and is there a directly labeled (ex. FITC) version of this antibody? I`m also working with AB8828, is this Ab. suitable for flow studies? Thanks

    Asked on Mar 25 2002

    Answer

    As far as we are aware, ab422 has not yet been tested in in flow cytometry. We do not stock a labelled version of this antibody. ab8828 also has not yet been tested in flow cytometry. If you do test these antibodies in FC, please let us know how you get on by submitting a summary of your results via the reviews section on the datasheets. In return we will forward a reward of your choice -- typically an Amazon gift voucher.

    Question

    I am using Ab422, the antibody that recognizes N-epsilon(gamma-glutamyl)Lys. To do appropriate control I need to get N-epsilon(gamma-glutamyl)Lys itself. Do you sell this peptide? Where to get it from?

    Asked on Jun 26 2001

    Answer

    The MAb to isopeptide shows good reactivity on cross linked protein containing isopeptide N-epsilon(gamma-glutamyl)Lys but has weak reactivity on free isopeptide. Therefore commercialy available free isopeptide from Sigma Chemical is not a good positive control.

    Question

    Please explain any differences between 153-81D4 and -81D1C2. I wish to perform both western blotting and immunohistochemistry for the isopeptide.

    Asked on Mar 26 2001

    Answer

    The difference between these two antibodies is the isotype: 153-81D4 is an IgM and 153-81D1C2 is an IgG1. They can both be used for both applications, so the choice is yours.
