Two chemical solutions need to be prepared for CLARITY execution. The hydrogel solution contains the monomers necessary to form a hydrogel within the tissue sample. The clearing solution is used to remove the unattached lipids from the tissue sample following hydrogel embedding.

Hydrogel Solution

The following table summarizes the ingredients of the hydrogel solution and their purpose. Amounts are listed for a 400 mL batch of solution.

Ingredient Amount Final Concentration Purpose
40% Acrylamide 40 mL 4% Hydrogel network monomer
2% Bis-acrylamide 10 mL 0.05% Small chemical crosslinker
VA-044 Initiator 1 g 0.25% Polymerization thermal initiator
16% Paraformaldehyde 100 mL 4% Biomacromolecule crosslinker
10X PBS 40 mL 1X Salt buffer
Deionized water 210 mL - Aqueous solvent

The hydrogel solution components should be kept cold on ice during the solution preparation to prevent polymerization. Following preparation of the stock solution, 40 mL aliquots can be distributed into 50 mL conical tubes, also kept on ice. This volume is ideal for the hydrogel embedding of a mouse brain sample, which requires 20 mL of hydrogel solution for perfusion and 20 mL for incubation and embedding (one tube per mouse brain).
