  • Relevance
    IgG is a monomeric immunoglobulin, built of two heavy chains gamma and two light chains. Each molecule has two antigen binding sites. This is the most abundant immunoglobulin and is approximately equally distributed in blood and in tissue liquids, constituting 75% of serum immunoglobulins in humans. This is the only isotype that can pass through the human placenta, thereby providing protection to the fetus in its first weeks of life before its own immune system has developed. It can bind to many kinds of pathogens, for example viruses, bacteria, and fungi, and protects the body against them by complement activation (classic pathway), opsonization for phagocytosis and neutralisation of their toxins. There are 4 subclasses: IgG1 (66%), IgG2 (23%), IgG3 (7%) and IgG4 (4%).

Thank you and your customer for your inquiry.

Unfortunately, the Kd (Dissociation constant) of ab7500 was not experimentally tested and we cannot provide any data for this.

But I can confirm that ab7500 is guaranteed for peptide ELISA with human samples by our Abpromise guarantee.

I am sorry I could not provide more data on this occasion and hope this information will nevertheless be helpful for your customer.

Thank you for calling Abcam yesterday.

For ab7500 it is specific to the Fc-region, unfortunately we have not determined the exact epitope. I have looked through the rest of our Human IgG antibodies and for those, they either do not recognize the CH1, or the epitope region has not been mapped and so we do not know where they bind.

I am sorry that I could not help further in this matter, but if there is anything else I can help with, then please let me know.

Thank you for your enquiry. We do not have MSDSs specific for each antiserum. The material safety datasheets are issued based on the inclusion of additional components such as Na Azide and Glycerol in addition to specific componds that we sell for particular techniques such as DAB for IHC etc. I hope this makes sense.
