  • To compose the fixative solution (Glutaraldehyde + Paraformaldehyde + NaPO4) for use in high-resolution light microscopy and electron microscopy studies.
[69]
  • To study the conjugation of goat anti-horseradish peroxidase with alkaline phosphatase by a reported method.
  • [63]
  • To compose the primary fixative, which is employed to protect the deterioration of cytoplasmic features of yeast cells during permanganate fixation.
