  • Target

    • Relevance
      Human cytomegalovirus (HCMV) glycoprotein B (gB) is an abundant virion envelope protein that has been shown to be essential for the infectivity of HCMV. HCMV gB is also one of the most immunogenic virus-encoded proteins, and a significant fraction of virus neutralizing antibodies are directed at gB.
    • Cellular localization
      Virus envelope.

    Antibody ab54023 has been tested in a neutralization assay that is described in the following reference. Figure 4 shows the data for this clone.

    Kirchmeier M et al. Enveloped virus-like particle expression of human cytomegalovirus glycoprotein B antigen induces antibodies with potent and broad neutralizing activity. Clin Vaccine Immunol 21:174-80 (2014).

    We do not test this antibody in a neutralization assay in-house so I do not have a protocol to send to you. A much simpler assay then the one used in the Kirchmeier paper is briefly described in the following paper. The assay involves counting PFU after incubation of virus with HCMV gB antiserum. The assay is described in the last paragraph of the paper. It does not mention applying this test to this clone or other monoclonal antibodies but it seems like an easy approach.

    EMBO J. 1986 Nov; 5(11): 3057–3063.


    The other HCMV antibody you have, ab6499, has not, to our knowledge, been used in a neutralization assay.

    Unfortunately, the Anti-Cytomegalovirus Glycoprotein B antibody [2F12] (ab6499), this antibody has not as yet been used in staining paraffin embedded sections to our knowledge. We do not have any other antibodies against this target which have been used in this application. However, this does not mean that it would not work, simply that we have not tried it and would therefore not be able to guarantee its performance in this application.

    If you would like to purchase ab6499 and use it with your tissue samples, you would be eligible to participate in the Abtrial scheme. This offer means that if you purchase ab6499 as normal, test the antibody with your samples in IHC-P and let us know of the results through an Abreview (no matter whether positive or negative) you would then be eligible to claim the value of ab6499 off any product in our catalogue. 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 ab6499.

    If ordered tomorrow you can expect to recieve the product by Thursday the 6th of December.

    I hope this information has been of help. If you require any further information please do not hesitate to contact us again.

    This antibody has never been tested against Rhesus CMV and 64% homology does not sound very promising - you would be better off with a polyclonal antibody. We are in the final stages of characterizing a chicken anti-CMV that may be applicable - will be available in the next month or so. If you need the single specificity (and has access to recombinant gB) perhaps the chicken polyclonal could be made monospecific via immunoaffinity purification.
