Cultispot assay

Abstract

The invention provides a method for detecting the production by cells in a sample of one or more analyte, which method comprises: (a) providing (i) a first binding protein which specifically binds to a first analyte; and (ii) optionally a second binding protein which specifically binds to second analyte; wherein said first binding protein and optionally said second binding protein are each immobilized at one or more discrete location within a well; (b) introducing a sample of cells into said well; (c) culturing said sample of cells under conditions suitable for: (i) release of said analyte and optionally said second analyte and optionally said one or more further analyte by said cells; and (ii) binding of said first analyte to said first binding protein and optionally binding of said second analyte to said second binding protein; and (d) determining whether or not said first analyte is bound to said first binding protein and whether or not said second analyte is bound to said second binding protein, thereby detecting production by a sample of cells of one or more analyte.
