The Cautionary Tale of GDF-15

2024-07-25T06:11:35+00:00July 24th, 2024|animal-free, Blog, News, protein science, quality, Resources|

Commercial sources of recombinant human GDF15 protein, in particular those purified from mammalian expression, are frequently contaminated with trace amounts of TGFβ and related proteins. These trace contaminants cause misleading experimental results due to the picomolar or even femtomolar EC50s of this family of cytokines.  Please be cautious with your source of recombinant GDF15 protein.
