SDS and heat are primary contributors to protein loss during the stripping process. Four sets of triplicate BMPA hydrogels with immobilized RNase-488 were exposed to (i) photobleaching only (control), (ii) just detergent (2% SDS), (iii) just heat (55–57 °C temperatures), or (iv) detergent and heat (2% SDS + 55–57 °C heat). At round 8, the combination of the detergent and heat condition had the greatest fluorescence intensity loss (61.1% ± 7.7%).
