Protein Polymer Technologies Inc. to Participate in Discovery Expo '97 In New York City

    SAN DIEGO, July 2, 1997 -- Protein Polymer Technologies, Inc. (Nasdaq: PPTI) announced that it will be participating in Discovery Expo '97 to be held July 9 at the New York Hilton and Towers.
    This third in a series of Discovery Expos organized by The Investment Reporter, a Newport Beach, CA-based financial newspaper, brings together small- and mid-cap companies with growth fund managers, analysts, stockbrokers and sophisticated investors.
    Protein Polymer Technologies, a San Diego-based biotechnology company, has developed a protein-based technology platform that allows the creation of new biomaterials which target multiple applications in biomedical markets.  The different classes of biocompatible polymers developed by PPTI have been genetically engineered to enable cell growth, promote the regeneration of tissue, bond to synthetic surfaces and resorb into tissue at controlled rates. Targeted applications include tissue adhesives and sealants, tissue augmentation, wound healing, surgical adhesion barriers and drug delivery vehicles.  PPTI's lead product ProLastin(TM)Plus is being developed in collaboration with Johnson & Johnson for use as a new generation surgical adhesive and sealant to replace or augment the use of sutures and staples.
