title: The preparation of heparan sulfate from the mitral valve of the human heart.
abstract: A study has been made of the glycosaminoglycan composition of the mitral valve of the normal human heart. Five glycosaminoglycans were isolated from tryptic digest of the material and were assayed by determining the carbohydrate content. Separation of these five polymers was achieved by Dowex 1 X 2 column chromatography. They were identified as hyaluronic acid, heparan sulfate, chondroitin-4-sulfate, dermatan sulfate and chondroitin-6-sulfate, respectively. As far as the authors are aware, this is the first isolation of heparan sulfate from the preparation of the mitral valve of the normal human heart.
