Useful in in vitro cell growth assays with possible applicability to a variety of problems in cellular pharmacology and biology.

Histochemical substrate for β-galactosidase.

X-gal

Used in chloride-selective solvent polymeric membrane electrodes. Also used in the production of TDMAC-heparin which is used as an antithrombogenic coating for catheters and tubing.

Anticoagulant. Heparin binds and activates the plasma protein antithrombin III which inhibits several enzymes in the blood coagulation cascade.

Used to stain DNA, RNA, and protein. Also useful for staining acid polysaccharides.

DNA stain blue

RNA stain bluish-purple

Protein stain red

Liquid anhydride for curing epoxy resins. This material is a mixture of methyl isomers of methylbicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic anhydride. The larger the proportion of NMA used in the epoxy resin formula, the harder the resultant block.

Water-soluble surfactant.

A nonionic surfactant useful in solubilizing protein aggregates. May also be used as a parting agent to facilitate removal of gels from tube walls.

Octylphenol-polyethyleneglycol ether; Octylphenoxypolyethoxyethanol

Under nitrogen in sealed ampoules.

Anionic surfactant, which will decrease polymer bead hydrophobicity and can additionally participate in charge stabilization of the suspension. SDS is a more rigorous surfactant than is commonly used in uncoated polymer bead preparations.

Catalyst for organic synthesis, minerals separation, reagent for alkaloids.

(silicotungstic Acid)

Used as a substrate for the histochemical demonstration of γ-glutamyl transpeptidase activity.

Forms solutions of low viscosity and high density, and can be used along with an aggregating agent like Ficoll 400 for qualitative in vitro isolation of pure lymphocytes from whole blood by gradient centrifugation.

Blocking reagent, lyophilized.
