Luminex magnetic carboxylated microsphere beads, or equivalent

The U.S. Food and Drug Administration, through the Office of Acquisitions and Grant Services within the Department of Health and Human Services, is soliciting Luminex magnetic carboxylated microsphere beads or equivalent products for use in fluorescent magnetic immunoassays to support viral research and review programs at the Center for Biologics Evaluation and Research. The solicitation, numbered 75F40126Q134073, was posted on June 9, 2026, with responses due by June 16, 2026, at 3:30 PM Central Time, and is conducted under full and open competition using a firm-fixed-price commercial product contract structure. The required beads must meet stringent technical specifications including carboxylated surface chemistry with COOH functional groups, superparamagnetic or paramagnetic properties for magnetic separation, compatibility with amine coupling chemistry such as EDC/NHS, and distinct fluorescent signatures detectable by flow cytometry. Four specific bead types are listed with quantities ranging from one to four units each, with all prices required to include shipping and be firm through September 30, 2026. Award will be made on a lowest priced technically acceptable basis, where technical acceptability is a mandatory gate—only quotes meeting all specification requirements will be considered, and the lowest-priced acceptable offer will be selected. All respondents must register in the System for Award Management, provide their Unique Entity ID, and complete all required representations and certifications, including those related to the Buy American Act, Section 508 accessibility, prohibitions on internal confidentiality agreements, combating human trafficking, and restrictions on contracting with inverted domestic corporations. Electronic submissions must be sent via email to Suzanne Martella, the contracting officer, and must exclude macros and executable files; violations result in non-responsiveness. Delivery must occur within 60 days of award to the specified CBER address in Silver Spring, MD, and cannot occur during federal holidays. Inspection and acceptance occur at destination by the Contracting Officer’s Representative, with full responsibility on the contractor to remediate any Section 508 accessibility nonconformities at their own expense. Invoicing must be submitted electronically through the Treasury’s Invoice Processing Platform, and payment is net 30 days following government acceptance, with no advance payments permitted. All contractors must comply with extensive FAR clauses including whistleblower protections, sustainable products, equal opportunity for workers with disabilities, and accelerated payments to small business subcontractors.
