Amplitude and frequency sweep tests for 30 mg/mL DDB gel and 1.5 mg/mL Matrigel gel. (a) The storage modulus G’ and loss modulus G’’ dependence on shear strain over a range 0.01–100%. Oscillation frequency 1 Hz, T = 37 °C. Mean n = 3–4. (b) The frequency sweep comparing G’ and G’’ over a frequency range 0.01–10 Hz. Shear strain 0.0005, T = 37 °C. Mean n = 3–4.
