Low background: the first RabMAb® advantage

Being monoclonals, rabbit monoclonal antibodies detect a single epitope so are less likely to cross-react with other proteins.

At the same time we have observed that rabbit monoclonals bind to their target with greater affinity enabling higher signal-to-noise ratio than mouse mAbs at a given concentration of antibody (1).

The benefit of this is that rabbit monoclonals typically provide more specific and sensitive detection of their target protein with low background.

"We have spent the last year buying AGR2 antibody from various companies and sometimes from the same company with different lot numbers, searching for an antibody that does not cross react with AGR3 and therefore is specific for AGR2, does not give us background when developing western blots, does not give us background in negative control when looking at immunofluorescent staining in tissue, and of course works well for both western blot and IHC.

We have finally found it!!"
