About this opportunity
The National Institute on Aging (NIA), part of the National Institutes of Health, has issued a sole source justification for DNA methylation microarray processing services valued at $279,496 to support the Baltimore Longitudinal Study of Aging (BLSA). The contract was awarded to the UCLA Neuroscience Genomics Core for processing 992 DNA samples at $281.75 per sample over a 12-month performance period. The sole source justification is based on the vendor's unique qualifications and extensive experience, having already processed over 3,500 samples for this ongoing longitudinal study. The agency determined that changing service providers would require costly comparability studies and could introduce technical variations that would compromise the research integrity of this long-term aging study, which evaluates genome-wide DNA methylation patterns in archived samples to understand epigenetic changes associated with aging. A sources sought notice posted on September 9, 2025, received no responses from other potential contractors, further supporting the sole source determination.
