Learn how to use this product The X-CLARITY™ Hydrogel Solution Kit is a pre-tested kit for uniform and consistent tissue-hydrogel hybridization. The kit is composed of X-CLARITY™ Hydrogel Solution and X-CLARITY™ Polymerization Initiator. X-CLARITY™ Hydrogel Solution, an acrylamide-based solution, is used to create polyacrylamide, a chemically inert and electrically neutral gel matrix. The X-CLARITY™ Hydrogel Solution contains no paraformaldehyde or bis-acrylamide. The X-CLARITY™ Polymerization Initiator, also known as VA-044, is a thermal free radical initiator. VA-044 is relatively stable at room temperature but, when heated in an aqueous solution, undergoes rapid hemolytic decomposition, releasing cationic free radicals that initiate the polymerization of hydrogel monomersRapid and consistent polymerization
