Arg₅-ELP_BC was characterized by temperature-programmed turbidimetry and DLS. The optical density at 350 nm (black line) indicated that Arg₅-ELP_BCs existed as soluble unimers with a R_h of <10 nm as determined by DLS (dots) up to 39 °C. At 39 °C Arg₅-ELP_BCs self-assembled into micelles with a R_h of approximately 20 nm that persisted up to 56 °C. Above 56 °C, Arg₅-ELP_BC formed micron-size aggregates.
