In Vitro

EW7195 inhibits the EMT, motility, and invasiveness of breast cancer cells in vitro. EW-7195 efficiently blocks TGF-β1-induced phosphorylation of Smad2 followed by the nuclear translocation of Smad2/3. EW-7195 blocks TGF-β1-induced mesenchymal morphology. EW-7195 inhibits TGF-β-induced transcriptional activation^[1].
EW-7195 (0.5-1 μM; 1.5 hours) efficiently inhibits TGF-β1-induced Smad2 phosphorylation^[1].

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.
