Tissue dissection, slicing, preparation, probing, staining, and analysis require tools that reliably produce high-quality samples. Any histology procedure involves embedding tissue followed by a slicing or chopping step for slide preparation. Microtomes, cryostats, freezing stages, and tissue choppers are available, as well as blades that cut embedded tissue to the desired thickness. Additionally, staining tools, such as automated stainers, are available for immunohistochemistry that is performed simultaneously.
