General description

Glutaraldehyde solution is 25% solution of glutaraldehyde in water. Antibacterial action of 2% solution of alkaline glutaraldehyde against various atypical mycobacteria has been investigated.

Application

Glutaraldehyde may be used in the following studies:
  • To compose the fixative solution (Glutaraldehyde + Paraformaldehyde + NaPO4) for use in high-resolution light microscopy and electron microscopy studies.
  • To study the conjugation of goat anti-horseradish peroxidase with alkaline phosphatase by a reported method.
  • To compose the primary fixative, which is employed to protect the deterioration of cytoplasmic features of yeast cells during permanganate fixation.
