Luminex magnetic carboxylated microsphere beads, or equivalent

The Food and Drug Administration's Office of Acquisition and Grant Services, specifically the Center for Biologics Evaluation and Research (CBER), is seeking sources for magnetic carboxylated microsphere beads, preferably Luminex MagPlex beads or equivalent products, to support viral research and review programs utilizing fluorescent magnetic immunoassays. This is a Sources Sought Notice (SSN) intended to identify small business sources capable of meeting the technical specifications for these specialized laboratory supplies. Key requirements include carboxylated surface chemistry, superparamagnetic or paramagnetic properties suitable for magnetic separation, compatibility with amine coupling chemistry (EDC/NHS), distinct fluorescent signatures identifiable by flow cytometry, minimum 20 distinct bead regions for multiplex applications, and compatibility with multi-laser flow cytometry systems. The notice targets small businesses within NAICS 325413 (In-Vitro Diagnostic Substance Manufacturing) with a size standard of 1,250 employees, though all interested parties may respond. Responses must be submitted by email to suzanne.martella@fda.hhs.gov by May 6, 2026 at 3:00 pm Central Time, and this is a market survey announcement only; no contract will be awarded, no reimbursement provided, and responses will not be considered adequate responses to future solicitations.

The procurement carries no small business set-aside designation and does not identify any incumbent contractors. The requirement specifies 46 distinct magnetic carboxylated microsphere bead sets in 1 ml volumes, with quantities totaling approximately 108 units across various bead types. Delivery is expected within 60 days of contract award to the FDA/CBER facility in Silver Spring, Maryland. Respondents must provide business information, SAM Unique Entity ID, past performance documentation within three years, technical specifications demonstrating capability to meet requirements, country of manufacture, GSA Schedule or government-wide contract information if applicable, warranty and payment terms, and informational pricing for market research purposes. While specific award values are not disclosed in this market survey notice, the quantity of approximately 108 units of specialized bead sets suggests a moderate procurement volume typical of laboratory research support contracts.
