The enzyme-linked immunosorbent assay (ELISA) is a fundamental laboratory technique with direct applications across scientific research and clinical diagnostics as well as everyday life. Unfortunately, many challenges exist that inhibit both its introduction and implementation in the high school biology classroom. We present a reliable yet inexpensive way of effectively simulating this assay, allowing student exposure to several advanced topics, including immunodetection, clinical diagnostics, and qualitative and quantitative colorimetric analysis.
