Glutaraldehyd

Glutardialdehyde is a fixing agent for specimens destined for morphological and enzyme histochemical analysis of samples of human origin.


The 25% Glutardialdehyde solution is used for the fixation of specimen for semi-thin cuttings and electron microscopy. Alternatively, especially sensitive material used for enzyme histochemistry, will be fixed with glutardialdehyde acc. to P.J. Anderson, purified and filled into ampoules under nitrogen. Sensitive enzymes e.g. endogenous peroxidase can often only be visualized in this way. It is registered as CE / IVD product for applications in diagnostics.
