The Department of Health and Human Services National Institutes of Health National Institute of Environmental Health Sciences (NIEHS) awarded a firm-fixed-price purchase order to Cytobank, Inc., a for-profit organization, for a Cytobank software license and associated cloud storage services. The potential value of the contract is $210,000.00, with a period of performance through May 14, 2024. The contract was awarded on a sole-source basis, as Cytobank was determined to be the only responsible source capable of providing the required services, which include a cloud-based platform for managing, storing, and analyzing single-cell flow cytometry data. The original opportunity was posted as a pre-solicitation notice, but no formal solicitation was issued. The contract does not have a set-aside designation.
