        The inventions listed below are owned by an agency of the U.S. 
    Government and are available for licensing in the U.S. in accordance 
    with 35 U.S.C. 207 to achieve expeditious commercialization of results 
    of federally funded research and development. Foreign patent 
    applications are filed on selected inventions to extend market coverage 
    for U.S. companies and may also be available for licensing.
    
    ADDRESSES: Licensing information and a copy of the U.S. patent 
    application and/or the issued patent referenced below may be obtained

    Monoclonal Antibodies for Binding HTLV-III (HIV-1) Proteins, and Cell 
    Lines for Their Production
    
    Sarngadharan, M., Veronese, F., Gallo, R. (NCI)
    Serial No. 06/816,573
    Patent Issued 27 June 89
    U.S. Patent No. 4,843,011
    Licensing Contact: Steven Ferguson, 301/496-7735 ext 266
    
        Monoclonal antibodies and hybridoma cell lines for their production 
    are disclosed for three specific proteins that characterize HIV-1, the 
    virus that has been identified with AIDS. This invention relates to all 
    monoclonal antibodies that demonstrate immune reactivity with specific 
    antigens that identify the HIV-1 virus: p41, a transmembrane envelope 
    glycoprotein; p24, a major core protein; and p17. These antibodies 
    provide a means for directly detecting the virus in the sera, blood or 
    blood products of AIDS patients or HIV-1 carriers. Such methods are an 
    important advance over the indirect antibody detection methods 
    presently used. Methods based on antibody detection give false 
    negatives if no antibodies have yet been produced. These antibodies are 
    believed to provide a positive indication of the presence of the virus 
    at any stage of the disease in a patient or in a healthy carrier of 
    virus.
    
    Sterile-Lyophilization Tube

    DHHS Reference No.: E-015-95/0
    Licensing Contact: David Sadowski, 301/496-7735 ext. 288
    
        Problem Addressed by This Invention: Many compounds, such as drugs, 
    growth factors, etc., must be kept sterile and must be aliquotted for 
    storage. Usually, these aliquots are best stored lyophilized. Yet, 
    researchers have never had a way to keep aliquots sterile through the 
    lyophilization process. Consequently, each aliquot has had to be 
    filter-sterilized when reconstituted for use. This process has the 
    disadvantages of consuming excessive filters, syringes, sterile, 
    receptacles, and time and results in serious loss of precious sample 
    due to absorption by the filters (especially with small aliquots less 
    than 1 ml). Alternatively, researchers have had to forego 
    lyophilization and store their solutions in the less-stable frozen 
    form.
        Solution Offered by This Invention: Sterile-lyophilization tubes 
    having a 0.22 micron filter built into the cap. This unique feature 
    allows a sterile solution to remain sterile throughout lyophilization, 
    even after the vacuum is released and air reenters the tube. Thus, a 
    starting solution is simply filter-sterilized while in a relatively 
    large volume, using a single filter and therefore suffering minimal 
    loss and consuming little time. It is then aliquotted into sterile-
    lyophilization tubes and lyophilized. The tubes can then be transferred 
    directly to the freezer, if desired. The compound is reconstituted when 
    needed, and may then be used immediately without further filtration.
        Potential Applications of This Invention: All researchers worldwide 
    who utilize sterile, labile compounds will have an interest in this 
    product, including governmental, university, institutional, and drug 
    company laboratories. Most notably in need are investigators involved 
    in drug-testing, which is normally done either in cell cultures, 
    laboratory animals, or humans, and which requires sterility of many 
    aliquots of many drugs. Additionally, this product will have a large 
    market relating to basic research utilizing microbial, plant, or animal 
    cell or organ cultures, to which sterile compounds such as growth 
    factors are commonly added. Research in drugs, growth factors, etc., is 
    expanding ever more rapidly, and generally requires a cell culture 
    system in which to study such compounds. Most of these compounds are 
    quite expensive. Loss of potency during storage and loss of material 
    during filtration are widespread problems which may be overcome with 
    this invention. Therefore, there exists a tremendous need, and immense 
    market for, this sterile-lyophilization vessel.
        Stage of Development: Development is complete and invention has 
    been successfully tested. Prototypes are available.
