Abstract: Embodiments of the current disclosure are directed to systems, methods and apparatus for evaluating single cell secretion profiles. In some embodiments, the apparatus may be configured to analyze substances expressed by a biological cell and may include a first compressible substrate, and a second substrate configured for removable sealing attachment with the first substrate. In some embodiments, upon attachment of the second substrate with the first substrate, an assembly is formed such that the open side of the plurality of chambers are covered by the second substrate, and a portion of each of the plurality of capture areas are exposed in each of the chambers.

Abstract: Disclosed are compositions and methods for the multiplexed analysis of one or more intracellular targets of a single cell. Exemplary compositions of the disclosure comprise a surface comprising a plurality of capture agents operatively-linked thereto, wherein each capture agent specifically binds to a distinct intracellular target and wherein the plurality of capture agents form a repeating pattern; a substrate comprising a plurality of chambers, wherein the substrate releasably couples with the surface and wherein each chamber of the plurality of chambers comprises at least one repeat of the repeating pattern of the plurality of capture agents of the surface; a coating composition comprising a cell lysis composition; and a linker composition comprising a functionalization component and an extension component.
