For those laboratories using other multicomponent acrylic systems, no alteration is necessary to the processing schedule. LR Gold LR gold is designed primarily for embedding unfixed tissue at low temperature. This enables enzyme histochemistry and immunocytochemistry of many fixation sensitive enzymes to be carried out in 1-4 micrometer resin sections. It is a non-toxic acrylic resin with low viscosity. The resin may be cured at -25 degrees Celsius using Benzil, a light sensitive initiator and a visible light curing source.

As this resin is both hydrophilic and stable in the electron beam, it is equally suitable for light and electron microscopy. With appropriate fixation, the same specimen may be used for both techniques. It may be thermally or cold cured, and it has been successfully used for immunocytochemical and immunohistochemical techniques. Further details are available upon request. LR white, soft.
