This opportunity requires a genotyping service to analyze tail DNA from genetically modified mouse lines for the NIAAA, NIH, with results needed within 24 hours of sample receipt. The contractor must process samples to detect 1 to 8 designated alleles per sample, email results, and store samples for a minimum of six months for potential retesting. The period of performance is July 2026 through July 2027. The work supports the Section on Neural Circuits at the NIAAA, with samples collected on-site. No budget amount is specified.
