Gelatin [9000-70-8] A2g .....................................................
Used for slide preparation for light microscope autoradiography and histochemistry. To make gelatin solution:
to 500ml of D.I. water at 60°C add 0.5g gelatin and stir to dissolve. After the gelatin is dissolved
add 0.05g of chromium potassium sulfate and let mixture cool to 40°C. Dip nitric acid cleaned slides into
warm gelatin mixture and dry in clean environment. Store prepared slides in clean slide box.

MW 302.3 mp 178-183° C 16 H 18 N 2 0 4
Used as a substrate for the histochemical demonstration of g-glutamyl transpeptidase
activity. Amino acid and chiral reagent. Purity based on dry form:
98% and Purity based on water content: 88%.
Glycerol, USP (Glycerine) [56-81-5] A2g ........................................
MW 92.09 bp 182°/20mm
Used as cryoprotectant to help prevent ice crystal damage to specimens. Substrate for
the assay of glycerol dehydrogenase, glycerol oxidase, and glycerokinase.
Heparin benzalkonium chloride complex CH6g .................................
An effective antithrombogenic coating when applied to a variety of materials used to make catheters
and tubing. For most materials a simple immersion of the device to be coated, air drying and sterilization
are sufficient to provide an antithrombogenic surface that will resist clot formation.
