The National Institute of Mental Health requires a Jess Automated Western Blot System, an automated capillary-based immunoassay system, including a warranty upgrade and operator training. The procurement is for a firm fixed-price purchase order and is not expected to exceed the simplified acquisition threshold. Questions from offerors are due by April 27, 2026, at 4:00 PM EST. The system must be manufactured by ProteinSimple, as it is uniquely required to meet the government's technical needs for reproducible, high-throughput protein analysis. The performance location is the National Institute of Mental Health's Molecular Imaging Branch.
