Recombinant human GDF15 (growth differentiation factor 15) protein is a 25 kDa disulfide-linked dimer composed of the mature domain of human growth differentiation factor 15 protein. Our recombinant GDF15 protein is expressed in E. coli and extensively validated to ensure no trace contamination of TGFβ, which can cause misleading results.
