Tissue Processing / Tissue Clearing

Tissue processing is the technique by which fixed tissues are made suitable for embedding within a supportive medium such as paraffin, and consists of three sequential steps: dehydration, clearing, and infiltration. In most clinical and research settings, tissue processing is accomplished using an automated tissue processor, with or without microwave-assistance. These techniques enable the deep imaging of large volumes of tissues using light microscopy approaches. Tissue clearing allows researchers to avoid time-consuming tissue sectioning approaches that can introduce artefacts and to examine biological tissues in their native, 3D state. Pre-owned histology equipment can be used to prepare and examine tissues while managing budget constraints effectively.
