Interpretive Summary:

Technical Abstract: Production of high quality antibodies is extremely important for the detection of low abundance proteins. Tristetraprolin (TTP), an anti-inflammatory protein, is such a very low-abundance protein in normal cells and tissues. Numerous laboratories and a few companies have produced TTP antibodies, but they are largely ineffective in detecting this protein in endogenous sources. We have raised TTP antibodies against recombinant proteins. These antibodies have been used successfully in the study of this protein by immunoblotting, immunoprecipitation, and immunocytochemistry procedures.
