  • Submucosa extracts
    Patent number: 6375989
    Abstract: A method for preparing a bioactive extract from warm-blooded vertebrate submucosal tissue is described. The submucosal tissue is extracted using an aqueous solution of extraction excipients, and the extracted bioactive components are then separated from the extraction excipients to provide an isolated extract enriched in bioactive components. The isolated extract is useful, inter alia, as additive for cell growth media to promote cell growth and proliferation in vitro.
