Glutaraldehyde should be stored at 4 degrees When making new aliquots of glutaraldehyde make sure to label them with the date so that we can throw them out
Glutaraldehyde has been a suggested alternative to formocresol as a tissue fixative for vital pulpotomy. Histologic studies showed that it produced rapid surface fixation of pulp tissue but with limited depth of penetration, so a larger amount of radicular pulp tissue remained vital.
What is the principle of glutaraldehyde fixation?
The principle behind the fixation is the binding of glutaraldehyde to nucleophiles of which the amino groups are the most abundant but binding to, e.g., sulfhydryl groups also occurs (Griffiths, 1993). The result is a crosslinking of the proteins of the cell (Kawahara et al., 1997), Figure 1.
How do you make glutaraldehyde fixation?
Add glutaraldehyde and paraformaldehyde to freshly prepared 0. 2) M sodium phosphate buffer while stirring constantly. Add H2O to a final volume of 1000 mL. Store aliquots (5-, 10-, 20-, or 50-mL) for up to 1 yr at -20°C.
