Glutaraldehyde solution, 50% w/w, may be used as a fixative for electron microscopy. In the laboratory, glutaraldehyde solution is commonly used as an amine-reactive homobifunctional crosslinker and as a disinfectant for medical equipment.

General description
Glutaraldehyde solution is 50% solution of glutaraldehyde in water.
Application
Cross-linking agent for gelatin,[1][2] poly(vinyl alcohol),[3] and polyheptapeptides.[4]
Glutaraldehyde may be used in the following studies:
To compose the fixative solution (Glutaraldehyde + Paraformaldehyde + NaPO4) for use in high-resolution light microscopy and electron microscopy studies.[5]
To study the conjugation of goat anti-horseradish peroxidase with alkaline phosphatase by a reported method.[6]
To compose the primary fixative, which is employed to protect the deterioration of cytoplasmic features of yeast cells during permanganate fixation.[7]
