4.03 Sole Source Justification Redacted.pdf

This is a Justification for Sole Source procurement document for simplified procedures under a Micropurchase Threshold (MPT) to Small Purchase Threshold (SAT) contract action.

The Naval Submarine Medical Research Laboratory (NSMRL) is procuring RNA Sequencing and Gene Expression Analysis Services on a sole source basis from Yale University, Yale Center for Genome Analysis (YCGA), CAGE Code 4B992, under purchase request 130137371-N6659626PR00050. The required services include RNA-Sequencing Library Prep Poly A (210 units), NovaSeq X Plus 25B 2x150 sequencing (1,875 units), Small Batch Analysis with differential gene expression and pathway analysis (1 unit), and Large Batch Analysis with differential gene expression and pathway analysis (2 units). The service delivery period runs from July 1, 2026 through June 30, 2027. The justification for sole source award cites Yale University's exclusive possession of government-approved research data, protocols, and established collaborations with NSMRL that are necessary to maintain data integrity and research continuity. The document indicates this is a logical follow-on to the expiring Contract N0018926PG015. No other known vendor can satisfy the government's specific research parameters related to cognitive fatigue biomarkers and warfighter health performance. The contracting officer from NAVSUP Fleet Logistics Center, Norfolk Contracting Department (Groton Contracting Office, Code 231.2) certified the sole source justification on June 3, 2026.
