Table 1. Transition temperatures for elastin-mimetic block sequences.

Polypeptide sequence Transition temperature (Tt)† Mechanical property
E1 [(VPGVG)2VPGEG(VPGVG)2]30 >75°C Elastomeric-like
E2 [(VPGVG)2VPGEG(VPGVG)2]48 >75°C
E3 [(VPGAG)2VPGEG(VPGAG)2]28 >75°C
E4 [(VPGIG)5]15 16°C
P1 [(IPAVG)2VPAVG(IPAVG)2]16 25°C Plastic-like
P2 [(IPAVG)5]33 21°C
P3 [(IPAVG)5]16 26°C
†

Tt is for an aqueous solution at 1 mg/mL. The Tt of P1 is an estimate based on the measurement of Tt from a triblock copolymer system with identical P1 endblocks separated by central E1 block [5].
