戊二醛溶液，Glutaraldehyde solution；Grade I, 25% in H2O, specially purified for use as an electron microscopy fixative

Glutaraldehyde, a saturated dialdehyde, is a high-level disinfectant and a chemical sterilant. Glutaraldehyde solutions contain both monomers and polymers with the difference in their fixation properties.

 

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

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.

 

Recommended for techniques demanding high purity.
