KRFK (TFA)

• UNSPSC Description:

  KRFK TFA, a peptide derived from TSP-1, can activate TGF-β. KRFK TFA promotes TGF-β-mediated signaling and its downstream role, independent of thrombospondin (TSP) receptors such as CD47 and CD36. KRFK TFA can be used for chronic ocular surface inflammatory disorders reseach[1].
