The VA intends to negotiate a sole source firm-fixed-price contract for MeDIP-seq and hMeDIP-seq DNA sequencing and data analysis services supporting traumatic brain injury (TBI) research at the William S Middleton VA Medical Center in Madison, WI. The estimated one-year performance period is August 10, 2026 through August 9, 2027, with work performed at the awarded vendor’s facility. The contractor will process adult and aged male/female mouse brain samples to identify methylation and hydroxymethylation changes after TBI, with deliverables including QC reports, raw sequencing data, analysis, and project summaries. Interested firms must submit capability information with references via email for evaluation to determine whether competition is possible. If no acceptable responses are received, the VA will proceed with sole source negotiation.
