Glutaraldehyde solution has been used:
- along with 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES) buffer to fix the concentrated extracellular vesicles (EVs) on concanavalin A for scanning electron microscope (SEM)
- as a component in a solution to fix the cells to observe its morphology
- to fix the Escherichia coli cells in aqueous solution to preserve the surface morphology of bacterial cells
Biochem/physiol Actions
Glutaraldehyde is applicable in biomedical research to fix cells and can also be used to analyze healthy and pathologic red blood cells.
