The Department of Health and Human Services, specifically the National Institutes of Health (NIH), intends to negotiate a sole source maintenance agreement with Carterra, Inc. for a 12-month service contract for the Carterra LSA XT Throughput instrument. This maintenance agreement is critical for the Antibody Biology Unit's research on monoclonal antibodies, particularly in developing therapeutics against diseases such as influenza, ensuring the instrument remains operational at all times. The contract includes essential services such as on-site support within three days of a request, preventative maintenance visits, software and firmware updates, and continuous phone support, with the performance period set from July 17, 2025, to July 16, 2026, in Rockville, Maryland. Interested vendors must submit a capability statement by May 15, 2025, demonstrating their qualifications to provide the required services, with all submissions processed through the NIH's electronic SIMPLIFIED ACQUISITION SUBMISSION SYSTEM (eSASS).
