The National Inst. of Health, National Cancer Inst. intends to procure Domino Image Analyzer from Optomax, 9 Ash Street, P.O. 840, Hollis, NH 03049. The Institute is investigating the effectiveness of several cancer vaccines in phase 1 clinical trials. One of the parameters for these studies is determining the antigen-specific T-cell precursor frequency in the peripheral blood lymphocytes in pre- and post immunized patients. The assay to be used is a filter immunoplaque assay, otherwise called the enzyme-linked immunospot assay (ELISPOT). The sensitivity of the ELISPOT assay is such that cells producing as few as 100 molecules of specific cytokine per second can only be detected using the Domino Image Analyzer from Optomax. This is not a request for competitive proposals, as no solicitation will be issued. However, vendors who believe they can meet the Government's requirement, may submit their qualifications. The submission must be in writing and must contain sufficient detail so that a determination can be made regarding meeting the Government's requirement. The submission must be received by COB August 26, 1996. (0215)
