London Resin Products
London Resin (L.R.) Products, L.R. White ® and L.R. Gold ® , are made in London, England and are
available to you from fresh stock held at Polysciences’ warehouses in Pennsylvania and Germany.
L.R. resins are a blend of hydrophilic monomers which exhibit low viscosity for rapid and thorough
penetration. Sections may be cut at 1-5 or ultra thin for EM work. Stable for one year when
stored at 4°C, these very low viscosity (8 cps) embedding media rapidly penetrate tissue due to
their hydrophilic nature.
L.R. Gold Embedding Media EH4d ............................................
L.R. Gold is a specialized material designed for cold processing of unfixed or
lightly fixed tissue. The product enables the researcher to study fixation sensitive
and temperature labile antigens and enzymes in resin sections using light
and electron microscopy. London Resin recommends the use of Poly(N-vinylpyrrolidone)
as a tissue protectant and either Benzil or Benzoin methyl ether as a
catalyst depending on the method of polymerization selected by the researcher.
L.R. White and L.R. Gold, are made in London, England, and are available to you
from fresh stock held at Polyscience’s warehouses in Pennsylvania and Germany.
LR resins are a blend of hydrophilic monomers which exhibit low viscosity for
rapid and thorough penetration. Sections may be cut at 1-5µ or ultra thin for
EM work. Stable for 1 year when stored at 4° C, these very low viscosity (8cps)
embedding media rapidly penetrate tissue due to their hydrophilic nature.

L.R. White Embedding Media H2g ............................................
Requires Cold Pack
L.R. White is the first low viscosity acrylic embedding medium product made by
London Resin Company. Used for routine light and electron microscopy, histochemisty
and immunohistochemistry, L.R. White can be cold or thermally cured.
Accelerator for room temperature curing of the resin is available for those appli-
cations where simple heat catalysis is inappropriate. L.R. White and L.R. Gold,
