99 -- ORIGEN IMMUNOASSAY SYSTEM SOL RFQ60130(NR) POC Marsha Gorham, Purchasing Agent, (301)402-4509, Patricia Haun, Contracting Officer, (301)402-4509. Under the authority of 41 USC 253(c)(1), FAR 6.302-1, the National Institutes of Health (NCI) intends to procure an Qrigen Immunoassay System from Igen Inc, 16020 Industrial Drive, Gaithersburg, Maryland, 20877. The Origen Tag-NHS ester is chemically designed in such a way that up to 25 of the tag labelling molecules can be coupled to a single protein thus providing much greater amplification of the electrochemoluminescence signal. This makes it an extremely sensitve detection system. This technology will enable NCI investigators to screen the library rapidly with much less sample and also to determine binding affinities of proteins which are selected for the library. The Origen system is the only known immunoassay system with this technology and benefits. It is the Government's belief that the requirements can only be met by Igen Inc. This notice of intent is not a requirement for competitive proposals, however, if an interested party believes they can meet the above specifications, they must submit their capablities, and furnish concise responses directed specifically to the requirements mentioned above. Information furnished shall include enough materials to perform a proper evaluation. Offerors will not be notified of the evaluation results. *** WRITTEN QUOTATIONS ARE REQUIRED, ALONG WITH DESCRIPTIVE MATERIAL OF THE PROPOSED ITEM WHICH MEETS ALL THE SPECIFICIATIONS ABOVE. QUOTATION WILL BE DUE 20 DAYS FROM THE RELEASE OF THIS SYNOPSIS. ***No collect calls will be accepted. See Numbered Note(s): 22. (0236)
