HOE 32020 is a Hoechst stain, a blue fluorescent dyes, used to stain DNA. Hoechst dyes are soluble in water and in organic solvents such as dimethyl formamide or dimethyl sulfoxide. Concentrations can be achieved of up to 10 mg/mL. Aqueous solutions are s
Gallocyanine is a small molecule blue dye used to stain nuclei. It is known to inhibit Dickkopf-1 (Dkk1), an antagonist of the Wnt pathway. Gallocyanine can disrupt the interaction of Dkk1 with its receptor LRP5/6 (IC50 = 3 μM), thereby activating Wnt/β-catenin signaling. Modulation of the Dkk1-LRP5/6 interaction via gallocyanine has been shown to inhibit prostaglandin J2-induced tau phosphorylation at serine396 in primary cortical neurons in vitro.
