Abstract

A method for rendering biological tissue sufficiently optically transparent for three-dimensional light microscopy imaging, comprising incubating biological tissue with an optical clearing solution, wherein the optical clearing solution comprises: (i) 20-50 wt % formamide, (ii) 10-90 wt % glycerol, and (iii) water as remainder. Also described herein is a method for ridding tissue of blood to make them amenable for optical clearing, comprising incubating biological tissue in a decolorizing solution, wherein the decolorizing solution comprises: (i) 0.5-3 wt % hydrogen peroxide, (ii) 0.05-1 wt % sodium azide, (iii) 5-20 wt % DMSO, and (iv) phosphate buffered saline as a remained. Also described herein is a method for reducing auto-fluorescence in biological tissue to permit imaging of the biological tissue in a fluorescence-based imaging technique with enhanced resolution, wherein the auto-fluorescence quenching solution comprises: 1-100 mM ammonium bicarbonate, (ii) 20-500 μM copper sulfate, (iii) 5-20 wt % DMSO, and (iv) water as remainder.
