Oscillatory rheology dynamic time sweeps and shear-thin recovery of 1 wt % MAX8, HLT2, AcVES3, and IE1 peptide gels in HEPES buffer (25 mM HEPES, 150 mM NaCl, pH 7.4) with 4 mg/mL encapsulated TIMP-2 monitoring the storage modulus (G′) as a function of time. The first 60 min represents the onset of gelation (strain = 0.2%, frequency = 6 rad/s), after which gels are shear-thinned at 1000% strain for 30 s and allowed to recover by reducing the strain to 0.2%. Recovery is monitored for an additional 60 minutes.
