Description

General description

Glutardialdehyde solution 25% - for electron microscopy, according to P.J. Anderson (purified and filled under nitrogen) Glutardialdehyde is a fixing agent for specimens destined for morphological and enzyme histochemical analysis of samples of human origin. Especially sensitive material used for enzyme histochemistry, will be fixed with Glutardialdehyde solution 25% according 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. Alternatively, the 25% Glutardialdehyde solution is used for the fixation of specimen for semi-thin cuttings and electron microscopy. Both are registered as CE / IVD product for applications in diagnostics. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.
