3、c acid,hyaluronate,and its salt forms,isthe simplest of the glycosaminoglycans.Hyaluronan is soluble in water and forms highly viscoussolutions.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
4、,and skin,as well as in cartilage.Hyaluronan has found uses in a variety of products ranging from viscosupplements(treatment ofosteoarthritis),adhesion prevention(prevention of post-surgical adhesions),viscoelastics(ocularprotection),and dermal implants(lip augmentation and wrinkle removal).New appl
5、ications,such asscaffolds for tissue engineering,are emerging.The aim of this guide is to identify key parametersrelevant to the characterization of hyaluronan for the development of new commercial applications ofhyaluronan for the biomedical and pharmaceutical industries.1.Scope1.1 This guide cover
6、s the evaluation of hyaluronan suitablefor use in biomedical or pharmaceutical applications,or both,including,but not limited to,Tissue Engineered MedicalProducts(TEMPs).1.2 This guide addresses key parameters relevant to thecharacterization and purity of hyaluronan.1.3 As with any material,some cha
7、racteristics of hyaluro-nan may be altered by processing techniques,such as cross-linking and sterilization,required for the production of aspecific formulation or device.Therefore,properties of fabri-cated forms of this polymer should be evaluated using testmethods that are appropriate to ensure sa
