LR White Resin is an electron microscopy embedding media, which can be used to study fixation-sensitive nuclear antigens. In addition, studies suggest that LR White Resin preserved fine nuclear structures better than Unicryl embedding via aldehyde fixation. Furthermore, LR White Resin is advantageous over other resins because this resin has low toxicity, low viscosity, and its hydrophilic properties make it beneficial to infiltrate specimens with ease. It also has low lipid solvency, which allows for membrane and cystosol structures to be seen under the microscope. LR White Resin shows great resolution when used in light microscopy, immunohistochemistry, transmission electron microscopy and retain superior antigenicity relative to other stains. Moreover, benzoyl peroxide has been created to specifically initiate the function of this resin.
