Our Abpromise guarantee covers the use of ab9243 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ELISA Use a concentration of 1 µg/ml.
IHC-Fr Use at an assay dependent dilution.
WB Use a concentration of 1 - 10 µg/ml. Detects a band of approximately 25, 50 -150 kDa. The antibody recognizes the heavy chains of human IgG. The size of the band observed depends on the sample preparation and degree of fragmentation the Ig molecule has undergone. Under reduced conditions in WB heavy chains at 50 kD. Intact (native) IgG is 150 kDa. Therefore either 50 kDa or the entire IgG at 150kDa will be observed, depending on how much the molecule is fragmented (you may see both).

I hope this is helpful. Please do not hesitate to contact us again, should you have any further question.

Thank you for contacting Abcam.

We have not tested any of those antibodies against monkey IgG, therefore I cannot say whether they will cross react or not. Due to this, you can take advantage of our testing discount program if you want, pleas...

Ab9243 has been used to identify human IgG in ELISA. The antibody's originator has not seen any cross-reaction to other isotypes. If you have any more questions please contact us again.

This antibody is specific for the human IgG heavy chain, but its epitope has not been mapped further. However, this antibody has been used to test chimeric antibodies where the Fab region is human. As ab9243 works well for this testing, one can assume ...
