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.

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.
iPSC-derived hypothalamic neuron differentiation activation by Smoothened agonist SAG 1 μM and purmorphamine 1 μM.
From Day 2 to day 9 to direct the cells toward ventral diencephalon with regular media change every 2 days.
