pI Marker Supply for Protein Analysis

The contract calls for the supply of isoelectric point markers or functionally equivalent substances to enable precise calibration of capillary isoelectric focusing systems across the full pH range of 3.0 to 10.17, with strict adherence to compatibility requirements for Maurice instrument platforms. These markers must deliver consistent, reproducible results essential for accurate protein characterization and analytical validation in regulatory environments. The procurement is tied to the FDA Office of Acquisition and Grant Services under the Department of Health and Human Services, and is structured as a subcontract to support ongoing laboratory operations requiring high-precision calibration standards. Responses are due by July 24, 2026, and the solicitation is classified under NAICS code 325414, indicating the production of pharmaceutical and biological chemical products. The procurement does not specify a set-aside designation or geographic performance location, suggesting flexibility in sourcing but requiring the supplier to guarantee product conformity, stability, and traceability. The materials must meet stringent quality standards to ensure reliable functionality within sensitive analytical workflows, with no room for deviation in pH resolution or marker behavior during use.
