Descrizione

Descrizione generale

Glutardialdehyde solution 25% - for electron microscopy, is a fixing agent for specimens destined for morphological and enzyme histochemical analysis. The 25% Glutardialdehyde solution is used for the fixation of specimen of human origin for semi-thin cuttings and electron microscopy. It is diluted with phosphate buffer(Potassium dihydrogen phosphate for analysis EMSURE^® ISO (Product number 1.04873) or di-Sodium hydrogen phosphate anhydrous for analysis EMSURE^® ACS,Reag. Ph Eur (Product number 1.06586)
to achieve the corresponding working concentration. Alternatively, especially sensitive material used for enzyme histochemistry, will be fixed with glutardialdehyde according to P.J. Anderson, purified and filled into ampoules under nitrogen (Product number 1.12179). Sensitive enzymes e.g. endogenous peroxidase can often only be visualized in this way. It is an IVD registered product and CE certified, thus can be used for clinical diagnostic purposes. For more details, please see instructions for use (IFU).
