Let Fisher Scientific help you find everything you need for use in your histology applications. Explore products by technical procedure:
In the fixation stage, a fixative is used to modify tissue by stabilizing the protein, so it is resistant to further changes. Thus, fixatives are used to protect tissue from degradation and to maintain the structure of the cells, including sub-cellular components, such as cell organelles (nucleus, endoplasmic reticulum and mitochondria).
In the processing stage, tissues must go through a dehydration process to replace water with the material that will be used for embedding, so the tissue samples adhere to the embedding material. The most common technique is paraffin wax embedding.
Samples are immersed in multiple baths of progressively more concentrated ethanol to remove water from the tissues, followed by a clearing agent, such as xylene, to remove the alcohol and finally hot molten paraffin wax, which replaces the xylene and infiltrates the tissue.
Various ease of use packaging configurations are available including FisherLOCK™ tamper-evident caps, EcoSafPak shipper and F-style bottles. These are specially filtered for use in histology applications.
