(Hayward, CA) is a precision medicine company developing products across indications on a proprietary active chromatin cell-free DNA (cfDNAac) platform. Because the platform requires deeply characterized patient material, Aqtual has built end-to-end biospecimen procurement infrastructure spanning US clinical sites and international collection partners, and now supplies that same material and capability to research partners across all major therapeutic areas. • Partners can acquire specimens alone, specimens with matched cfDNAac data, or commission prospective collection with molecular profiling built into the protocol. cfDNAac data generation may require an additional SOW through Scientist.com's biomarker service contract.
