Biological Activity for SAG

SAG is a potent Smoothened (Smo) receptor agonist (Kd = 59 nM); antagonizes Cyclopamine (Cat. No. 1623) action at the Smo receptor. SAG potently activates the Hedgehog signaling pathway in Shh-light 2 cells (EC50 ~ 3 nM) and induces pathway activation independently of Ptch proteins. SAG is a putative inhibitor of a cellular component required for Hedgehog signaling and also enhances neuronal differentiation of iPSCs into dopaminergic neurons.

SAG dihydrochloride (Cat. No. 6390) also available.

Promoted the formation of cilia.
By Kishor Pant on 02/10/2023
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: HepG2, and Huh,

SAG consistently produced positive results in our experiments; it promoted the formation of cilia and reduced the proliferation of cancer cells.

We use 5-20 nm concentration for 24-48 hours.
