Assay.Works' library of 150,000 small molecule compounds originates from the screening deck of a renowned bio-pharmaceutical enterprise enriched with compounds from a leading commercial supplier. It has been exclusively designed by experienced computational chemists and meticulously curated for optimal lead-likeness and diversity. To ensure the quality of compound samples in the library, molecular mass and purity have been verified by LC/UV/MS analysis during admission.
Assay.Works sets itself apart with its state-of-the-art compound management facility. A cutting-edge acoustic dispensing platform allows to precisely dispense quantities ranging from nanoliters to microliters, resulting in significant resource savings. Sample management operations, including compound registration, screening plate production, and inventory management are backed by Mosaic Sample Management, a leading LIMS solution.
