Abstract: Embodiments of the invention are directed toward methods and devices for constructing assay arrays including a combination of constituent compositions from constituent arrays. The combined compositions are evaluated, in some embodiments of the invention, to identify combinations with a combination effect. Other embodiments of the invention are directed toward constructing constituent arrays in various configurations to facilitate the production of assay arrays. Such embodiments include: constructing constituent arrays and assay arrays with corresponding composition and assay control sets; constructing constituent arrays with a unique set of origin locations and corresponding sets of derivative locations; varying the concentrations utilized for a constituent composition; and composing assay arrays corresponding to a virtual sparse assay array. Other embodiments of the invention are directed towards systems and method of evaluating the activity of combined compositions in an assay array.
