Monitoring SNR of immobilized protein targets from BMPA hydrogels during chemical stripping. (A–C) SNRs of the photobleaching controls, the buffer controls, and the treatment group, respectively. The SNRs of the photobleaching control gels demonstrate minimal fluctuation over 29 incubation cycles, whereas the SNRs of the buffer control gels demonstrate a steady decrease for the first 14–16 cycles, followed by a plateau. The SNRs of the treatment group demonstrate a dramatic decrease during the first 3–5 rounds of stripping, followed by a plateau for the remaining rounds. For all plots, each trace represents the SNR from one ROI in a BMPA hydrogel.
