The effects of two toxins, sodium cyanide (NaCN) and ionomycin (IM), on neuronal viability and on the expression of the microtubule-associated proteins MAP1, MAP2, and tau were studied in isolated chick cortical neurons. Cytotoxic hypoxia due to NaCN treatment was performed to mimic acute neuronal damage, whereas long-term IM treatment was used as a model(More)
Formalin fixation is known to inactivate most viruses in a vaccine production context, but nothing is published about virus activity in tissues treated with alternative, non-crosslinking fixatives. We used a model assay based on cell culture to test formalin and PAXgene Tissue fixative for their virus-inactivating abilities. MDCK, A549, and MRC-5 cells were(More)
BACKGROUND Requirements on tissue fixatives are getting more demanding as molecular analysis becomes increasingly relevant for routine diagnostics. Buffered formaldehyde in pathology laboratories for tissue fixation is known to cause chemical modifications of biomolecules which affect molecular testing. A novel non-crosslinking tissue preservation(More)
Molecular diagnostics in personalized medicine increasingly relies on the combination of a variety of analytical technologies to characterize individual diseases and to select patients for targeted therapies. The gold standard for tissue-based diagnostics is fixation in formalin and embedding in paraffin, which results in excellent preservation of(More)
