Fresolimumab  (Synonyms: GC1008)

Fresolimumab (GC1008) is a human monoclonal antibody against TGF-β that neutralizes all mammalian active subtypes of TGF-β. The binding affinity of Fresolimumab to TGF-β2 is 1.8 nM. Fresolimumab radiolabeled with ⁸⁹Zr can be used for PET analysis of TGF-β expression, antibody uptake and organ distribution. Fresolimumab can be used in the study of cancer, osteogenesis imperfecta, fibrosis and kidney disease^[1][2][3].
