Now let’s download ASTM F2347-15,Standard Guide for Characterization and Testing of Hyaluronan as Starting Materials Intended for Use in Biomedical and Tissue Engineered Medical Product Applications.
ASTM F2347-15 covers the evaluation of hyaluronan suitablefor use in biomedical or pharmaceutical applications, or both,including, but not limited to, Tissue Engineered Medical Products (TEMPs).
ASTM F2347-15 addresses key parameters relevant to thecharacterization and purity of hyaluronan.
The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.
Hyaluronan, which in this guide will encompass hyaluronic acid, hyaluronate, and its salt forms, is
the simplest of the glycosaminoglycans. Hyaluronan is soluble in water and forms highly viscous solutions. Hyaluronan is found in ubiquitously in the body as part of the extracellular matrix of tissues with high concentrations in the synovial fluid, vitreous humor, and skin, as well as in cartilage.
