The Department of Health and Human Services, specifically the National Institutes of Health (NIH), intends to award a sole source contract to Illumina, Inc. for maintenance services on two Illumina NextSeq™ 1000 Sequencers. The contract will cover comprehensive support, including parts, labor, travel, and technical assistance, essential for high-throughput next-generation sequencing used in diagnosing inherited immune disorders. This acquisition is critical as Illumina is the sole manufacturer with the necessary components and expertise to maintain the equipment to its original specifications. Interested parties capable of providing similar services may submit a capability statement to Kimala Winfield at kimala.winfield@nih.gov or Malinda Dehner at dehnerm@cc.nih.gov, with submissions due by the specified deadline.
