  • Application notes
    Is unsuitable for IP.
  • Target

    • Relevance

      There are four IgG subclasses (IgG1, 2, 3 and 4) in humans, named in order of their abundance in serum (IgG1 being the most abundant). IgG2 is the only IgG subclass which passes through the placenta at a level generally lower than that found in the mother. A deficiency of IgG2 indicates a poor antibody response to bacterial polysaccharides and can lead to increased susceptibility to infections caused by encapsulated bacteria.

      Question

      Can you please let me know if any of the following Anti- human IgG2 primary antibodies cross react with Rhesus IgG2?    I am also interested in purchasing Anti- human IgG3 and IgG4  primary antibodies that recognize Rhesus IgG3 and IgG4, respectively.

      Asked on Dec 07 2012

      Answer

      I have reviewed these products and have been in touch with the labs regarding reactivity with Rhesus as requested. We would not recommend any human IgG2 antibody which we know is directed to the hinge region, such as ab1935, against Rhesus as the homology of these is poor. However with this exception, in general there seems to be good homology between Rhesus and Human IgG subtypes. More information about human and Rhesus IgGs may be found at the links below: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1782391/ http://nhpreagents.bidmc.harvard.edu/nhp/macaqueisotypes.aspx http://www.kcl.ac.uk/immunobiology/Mac_ig/ We have not tested any of these products against Rhesus. For UNTESTED applications, we have established a testing discount program. Here is a brief description of how it works: The testing discount program is for customers who like to use an antibody/protein on an untested species/application. You would purchase the antibody at full price, test it and submit an Abreview with your data (positive or negative). On your next order you will receive a discount equal to the value of the product tested. The terms and conditions of this offer can be found here: https://www.abcam.com/AbTrial We could also offer enrollment in the AbTrial program for anti-IgG4 ab109493. We do not currently have any anti-IgG3 primary antibodies. More information about ab109493 can be found at the locations below: Rabbit monoclonal [EP4420] to IgG4: https://www.abcam.com/igg4-antibody-ep4420-ab109493.html
