Glutaraldehyde solution, 25 wt. % in H₂O is an aqueous solution of glutaraldehyde, an aliphatic dialdehyde also known as glutaric dialdehyde or pentane-1,5-dial. Glutaraldehyde contains two reactive aldehyde groups and can react with primary amine-containing compounds, making it a useful crosslinking and fixation reagent in biochemical, histological, and microscopy-related applications.

This product is commonly used as a protein crosslinker and fixative for biological samples. It helps preserve cellular and tissue structures by crosslinking proteins and other biomolecules, making it suitable for specimen preparation prior to microscopic observation, histochemistry, cytochemistry, and related morphological studies.

Application:

• As a fixative for biological specimens in light microscopy and electron microscopy sample preparation.
• As a protein crosslinking agent, especially for amine-containing biomolecules and polymers.
• For cell and tissue fixation prior to staining, SDS-PAGE-related preparation, histological observation, or ultrastructural analysis.
• In histochemistry and cytochemistry workflows to preserve cellular morphology.
• For enzyme immobilization and other biochemical conjugation or crosslinking applications.
• As a crosslinking reagent for materials such as gelatin, poly(vinyl alcohol), and other amine-containing polymer systems.
