Hyaluronan (HA) is an ubiquitous extracellular matrix polymer that plays many roles in health and disease. The ability to view the spatial and temporal expression of HA in tissues and on/in cells has provided researchers with insights into the tremendously diverse biological processes in which HA is involved. Biochemical extraction, quantity, and size measurement of HA can tell part of the story, but these techniques are incomplete in placing HA at the scene of a biological event and determining which other molecules are likely to be cooperating. HA, however, is not immunogenic, so preparing antibodies for histochemistry is problematic. Fortunately, a probe for HA was devised based on the HA binding region of aggrecan, and today this probe is commercially available and very useful for histochemistry. This article discusses the conditions and considerations that the authors' lab and others have developed for optimal HA staining in many tissues and cell types.

The Extracellular Matrix
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...
Matrix Proteoglycans and Glycoproteins
Glycosaminoglycans
GAGS are found in the extracellular matrix of vertebrates, invertebrates, and bacteria. Due to their polar nature they attract water, and serve as excellent lubricants or shock absorbers in an animal body.
