Background Sample preparation is the first step in the evaluation of tissue samples. In this research tried to using two types of formalin and Bouin fixative ovarian tissue morphogenesis be evaluated practical. MaterialsAndMethods Ovaries of 6-8 week-old Naval Medical Research Institute female mice were randomly divided into 3 groups: Ι. Ovaries that immediately fixed in Bouin’s fixative; II. O...
Formalin-fixed tissue has been a mainstay of clinical pathology laboratories, but formalin alters many biomolecules, including nucleic acids and proteins. Meanwhile, frozen tissues contain better-preserved biomolecules, but tissue morphology is affected, limiting their diagnostic utility. Molecular fixatives promise to bridge this gap by simultaneously preserving morphology and biomolecules, en...
The rate at which the transmitter release machinery is fixed by 2% glutaraldehyde at hippocampal synapses and the amount of release evoked by the fixative have been investigated. We recorded from hippocampal cells while fixative was applied with a rapid flow system. Release is blocked in less than a second and fixative-produced exocytosis is at most a few percent of what would be caused by a hy...
