The National Institutes of Health (NIH) intends to award a non-competitive purchase order to REPROCELL, Inc. for DNA and RNA extraction services from blood and multiple tissue types. This requirement supports an ongoing animal study and involves extraction and quality control for approximately 320 DNA and 240 RNA samples. The action is a continuation of prior work, requiring the same vendor to ensure methodological consistency and data comparability. No specific budget amounts, performance location, or submission timelines are mentioned in the description. This opportunity is limited to a single source due to the need for scientific integrity and continuity.
