Glutaraldehyde for electron microscopy: a practical investigation of commercial glutaraldehydes and glutaraldehyde-storage conditions

The Histochemical Journal, 1995
The paper takes issue with the use by glutaraldehyde suppliers of the term 'for electron microscopy', and the common practice of researchers giving insufficient or no data about the glutaraldehyde they use. Investigation of 11 commercial glutaraldehydes recommended for electron microscopy shows that only three or four of them are adequate for this ...

Glutaraldehyde: Nature of the reagent

Journal of Molecular Biology, 1972
Abstract Aqueous solutions of glutaraldehyde used for the chemical modification and stabilization of proteins have been found to consist of free glutaraldehyde (I), the cyclic hemiacetal of its hydrate (II) and oligomers of this (III) in equilibrium with each other.

Subcellular localization of glutaraldehyde

Dental Traumatology, 1990
Abstract Glutaraldehyde (GA) has been proposed as an alternative to formocresol for pulpotomies in primary teeth and as an irrigant in root canal therapy. These studies were undertaken to determine if GA can associate with the nucleus of living cells, thereby posing a mutagenic threat.

Glutaraldehyde Nonbiologic Monitors

Infection Control & Hospital Epidemiology, 1990
Glutaraldehyde was first synthesized by Harries and Tank in 1908, and first marketed as a chemosterilizer in 1963. Since that time, glutaraldehyde has been used extensively as a disinfectant and chemical sterilizing solution. Even though it is generally agreed that moist heat is the preferred method of sterilization for medical, dental and hospital ...

Glutaraldehyde—its purity and stability

Histochemie Histochemistry Histochimie, 1972
Six commercially available glutaraldehydes were tested spectrophotometrically for their purity. These results were compared with glutaraldehyde purified by two experimental techniques. Ten sets of storage conditions were chosen and aliquots of purified glutaraldehyde were stored under these conditions for eight months.

Modification of a catalase by glutaraldehyde

Applied Biochemistry and Microbiology, 2006
Polycondensation of a catalase (EC 1.11.1.6) with glutaraldehyde in order to stabilize the quaternary structure of an enzyme, maintain its activity, and protect it from thermal denaturation was studied. Synthesis showed a superequivalent utilization of the aldehyde groups relative to the catalase amine groups, as a result of the formation of ...

The fixation of nuclei in glutaraldehyde

Journal of Cell Science, 1977
ABSTRACT The production of an artifactual network in the nuclear sap of the salivary glands of Drosophila has been investigated. Mechanical stress to the cells, 3 % glutaraldehyde containing more than 4 mM calcium, tannins, or cacodylate buffer or whose temperature is above 10 °C all enhance this artifactual effect.

Reaction of proteins with glutaraldehyde

Archives of Biochemistry and Biophysics, 1968
Abstract Glutaraldehyde was found to react with the α-amino groups of amino acids, the N-terminal amino groups of some peptides and the sulfhydryl group of cysteine. The phenolic and the imidazole rings of tyrosine and histidine derivatives were partially reactive.

Biological effects of residual glutaraldehyde in glutaraldehyde‐tanned collagen biomaterials

Journal of Biomedical Materials Research, 1980
AbstractGlutaraldehyde is commonly used to control physical and biological properties of collagen structure by means of intramolecular and/or intermolecular crosslinking of collagen molecules. Solubility, antigenicity, and biodegradation of naturally occurring or reconstituted collagenous matrices are effectively reduced by glutaraldehyde treatment ...

Safe use of glutaraldehyde

Nursing Standard, 2000
Glutaraldehyde is an effective chemical for killing micro-organisms that is used in a variety of healthcare settings to rapidly clean instruments. It is highly toxic in even small concentrations and needs to stored and handled carefully. Diane Romano-Woodward explains how nurses can ensure that adequate precautions are taken to prevent harm to staff ...
