Glutaraldehyde is used for cross-linking proteins and polyhydroxy materials. Also used as a fixative for tissues and as an amine-reactive homodifunctionalized crosslinker. It is also used in coupling reaction of biotin hydrazides to nucleic acids which is useful for conjugating fluorescent hydrazides and hydroxylamine’s to DNA and for stabilization of proteins on agarose beads, activation of polystyrene and glass, for immobilization of antibodies and antigens.
