Arraystar Inc.

Arraystar Inc., a for-profit genomics and molecular biology services firm based in Rockville, Maryland, operates as a prime contractor delivering specialized DNA and RNA sequencing services to federal research agencies, competing full-and-open with no set-aside designations across its federal footprint.

Arraystar's capability portfolio centers on epigenetic and transcriptomic sequencing services: methylated and hydroxymethylated DNA immunoprecipitation sequencing (MeDIP-seq and hMeDIP-seq), exosome miRNA profiling, transfer RNA sequencing, and miRNA sequencing. The vendor's recent work reflects this narrow technical focus. A $110,044 firm-fixed-price definitive contract awarded by Veterans Integrated Service Network 12 on September 15, 2026 covers MeDIP-seq and hMeDIP-seq services supporting traumatic brain injury research at the William S. Middleton VA Medical Center in Madison, Wisconsin, with deliverables including sample quality control reports, raw sequencing data in Fastq format, and data analysis results in Excel, PDF, and PNG formats; ultimate completion is September 14, 2027. Earlier follow-on work on the same research program produced a $77,700 contract from the VA (March 1, 2025) for identical services. The Food and Drug Administration issued a $21,480 purchase order (August 1, 2023) for transfer RNA sequencing and a $16,514 purchase order (September 19, 2023) for exosome miRNA profiling, both performed in Rockville or Silver Spring, Maryland.

Customer concentration is diffuse across HHS components. The Food and Drug Administration leads by award count (13 awards, $202 thousand combined potential value), but the Army Medical Command dominates potential value (2 awards, $321 thousand). The top five funding agencies account for 80% to 82% of recent awards and dollars: FDA, the National Institute on Aging, the Centers for Disease Control and Prevention Pittsburgh, the National Heart Lung and Blood Institute, and the National Cancer Institute, with secondary exposure to the Veterans Health Administration and the Army Medical Command. All work classifies under NAICS 541711 (Research and Development in Biotechnology) or 541380 (Testing Laboratories and Services); PSC coding splits between Reference Laboratory Testing and Special Studies/Analysis—Chemical/Biological.

Arraystar operates exclusively as a prime contractor (100% of recent awards). Activity has remained flat in recent years: two awards in 2021, one in 2022, three in 2023, zero in 2024, one in 2025, and one in 2026. The combined potential value across all 49 federal awards in the source is $1.2 million, with $1.2 million obligated (100% draw-down). Only one award faces ultimate completion within the next twenty-four months ($110 thousand potential value). The vendor holds no parent contract vehicles (GWACs, BPAs, or agency IDIQs) and places no subcontract work.
