Description

General description

Glutaraldehyde (Glutaric dialdehyde, Pentane-1,5-dial) is an aliphatic dialdehyde widely utilized as a versatile biochemical reagent. Glutaraldehyde solutions contain both monomers and polymers with the difference in their fixation properties. Its applications include serving as a protein crosslinker, facilitating enzyme immobilization in microscopy, histochemistry, and cytochemistry. This compound acts as an amine-reactive homobifunctional crosslinker and a cell fixative before SDS-PAGE, staining, or electron microscopy, making it suitable for diverse morphological studies.
Glutaraldehyde efficiently crosslinks amine and hydrazine derivatives to proteins and other amine-containing polymers. Notably, it has been used in certain reactions to directly couple biotin hydrazides to nucleic acids, suggesting potential applications in conjugating fluorescent hydrazides and hydroxylamines to DNA. In histology studies, Glutaraldehyde is employed to preserve tissue sections, preparing them for closer examination.

Application

Glutaraldehyde solution has been used:

• to fix the blood samples for scanning electron microscopy (SEM)
• to fix scaffold pieces for SEM analysis
• in drug treatments to treat K562 (leukemia) cells to permanently cross-link cell components

Biochem/physiol Actions

Glutaraldehyde can be used in biomedical research to fix cells. It can also be used as a tool to investigate healthy and pathologic red blood cells. Medical equipment like spirometry tubing, endoscopes, dialyzers, hemodialysis proportioning and dialysate delivery systems, endocavitary probes, transducers, anesthesia and respiratory therapy equipment, and reuse of laparoscopic disposable plastic trocars can be disinfected with glutaraldehyde.

Features and Benefits

• Versatile and adaptable for wide variety of research applications
• Ready-made solution reduces the need for preparation time
