Plot of transition temperature as a function of 1/length of ELP pentapeptid×103 for ELPs and thioredoxin-ELPs. The transition temperature was measured from 25 μM solutions of ELP and Trx-ELP in PBS, and the data supports a linear relationship between Tt and 1/ELP length similar that observed for other ELPs.30 Linear regression shows r2=0.986 for ELP[KV7F], r2= 0.983 for Trx-ELP[KV7F], and r2=0.977 for Trx-ELP[KV2F]. Goodness of fit could not be established for ELP[KV2F] polymers because only two of the four expressed ELP[KV2F] proteins have measurable Tt (below 90°C) at 25 μM in PBS.
