Abstract
The impact of mechanical cues on cell behavior is increasingly being recognized, rendering hydrogel platforms that mimic the extracellular matrix indispensable in in vitro cell biology research. Here, we present a step-by-step protocol for synthesis and rheological characterization of polyacrylamide (PAAm) hydrogels with varying stiffnesses, produced as large circular unattached gels customizable in shape and size. We outline methods for their use in cell culture and downstream applications involving secretome or cell analysis, and protein visualization by fluorescence microscopy.
