Abstract:
1. A method of detecting a cell product, comprising: a) providing a reaction chamber comprising: a cell culture medium and detection substrate having a capture reagent immobilized thereon that binds to said cell product to form a cell product-capture reagent complex; b) adding a sample of cells to said reaction chamber; said cells producing said cell product, said product binding to said capture reagent forming a cell product-capture reagent complex at a location on said substrate near said cell; c) adding a detection reagent/detection particle complex to said reaction chamber, said detection particle having a characteristic spectrographic feature, said detection reagent/detection particle complex binding to said cell product-capture reagent complex producing a detection reagent/detection particle-cell product-capture reagent complex; d) washing away detection reagent/detection particle complexes not bound to said product-capture reagent complex, and e) detecting said detection reagent/detection particle-cell product-capture reagent complex visually or via image analysis as a spot on said detection substrate.
