ELP surface charge as measured by zeta potential in 1X PBS pH 7.4, below and above their respective transition temperatures. The constructs are ordered as follows: a L20, b L40, c L80, d L160 and e V40. Measurements taken at 5 °C are represented by filled triangles while those at 37 °C are represented by filled squares. Reported values represent the mean ± standard deviation with an n = 3. *p < 0.05, **p < 0.005 and ***p < 0.0001
