Based on 4 publication(s) in Google Scholar

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

IC₅₀ & Target

TGF-β^[1]

All TGF-β Receptor Isoforms :

In Vitro

KRFK (50 μM; 24 h) activates the secretion of TGF-β and reduces the expression of DC maturation markers in tsp-1 deficient bone marrow-derived dendritic cells (BMDCs) ^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

KRFK (5 μg/5 μL/eyes; single dose) significantly prevents the development of chronic ocular surface inflammation in TSP-1^-/- mice^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
