Virtually all applications of glutaraldehyde exploit its high reactivity toward proteins. Being nonvolatile and bifunctional, glutaraldehyde is often preferred to the less expensive formaldehyde. It reacts with amines, amides, and thiol groups in proteins.
Glutaraldehyde is used in biochemistry applications as an amine-reactive homobifunctional crosslinker and fixative prior to SDS-PAGE, staining, or electron microscopy. It kills cells quickly by crosslinking their proteins and is usually employed alone or mixed with formaldehyde as the first of two fixative processes to stabilize specimens such as bacteria, plant material, and human cells. A second fixative procedure uses osmium tetroxide to crosslink and stabilize cell and organelle membrane lipids. Fixation is usually by dehydration of the tissue in ethanol or acetone, by embedding in an epoxy resin or acrylic resin.
A solution of glutaraldehyde, typically of 10% w/w, is sold under various trade names to remove common and plantar warts. It is said to inactivate viruses and bacteria, and to dry the skin, facilitating physical removal of the wart. Trade names include Diswart Solution and Glutarol.
