Notice of Intent to Sole Source – Adaptive Biotechnologies Corporation RFP

Description: This special notice announces the National Institutes of Health Clinical Center's intent to make a fixed-price, sole-source purchase order to Adaptive Biotechnologies Corporation for proprietary clonoSEQ assay reference laboratory testing services. The requirement supports minimal residual disease testing for immunocompromised patients and patients with advanced hematologic malignancies because the Department of Laboratory Medicine lacks the necessary in-house capabilities, equipment, and reagents. It is a procurement notice rather than a grant or request for quotations, and interested parties could submit capability information by September 25, 2026, at 9:00 AM EDT.
