Appreciation of the different methods of tissue handling is a prerequisite to obtaining accurate and biologically relevant tissue-based information. When a tissue sample is removed from its ...

For histological investigations of biological tissues, i.e. anatomical studies under the microscope, samples are usually fixated to prevent them from decaying. Fixation is typically done by immersing ...

The reflecting cells on the scales of sprat and herring contain ordered arrays of guanine crystals. The spacing of the crystals within these cells determines the wave bands of the light which they ...

A basis for the interpretation of the structure of the cell membrane is often looked for in electron microscope investigations on the structure of lipid models. A difficulty in these investigations is ...

The analysis of gene expression by growth plate chondrocytes in vivo has been hampered by the inherent difficulty in performing in situ hybridization on mineralized tissues. The combination of laser ...

For histological investigations of biological tissues, i.e. anatomical studies under the microscope, samples are usually fixated to prevent them from decaying. Fixation is typically done by immersing ...

High pressure freezing (HPF) is used to freeze samples in milliseconds without significant ice crystal damage. Chemical fixation at room temperature takes order of magnitude longer because it takes ...
