SAG (0.1 nM-100 μM; 30 h) induces firefly luciferase expression in Shh-LIGHT2 cells with an EC50 of 3 nM and then inhibits expression at higher concentrations[1].
SAG (1-1000 nM; 1 h) competes for the binding of BODIPY-cyclopamine to Smo-expressing Cos-1 cells, yielding an apparent dissociation constant (Kd) of 59 nM for the SAG/Smo complex[1].
SAG (100 nM) inhibits the inhibitory effect of ShhN-induced pathway activation by Robotnikinin[2].
SAG (250 nM; 48 h) significantly increases SMO mRNA and protein expression in MDAMB231 cells[3].
