Abstract:
1. A viscoelastic hydrogel, comprising: a first protein hetero-assembled with a second protein, wherein the first protein cannot self-assemble with itself, wherein the second protein cannot self-assemble with itself, wherein the first protein includes a first association sequence (1stA) and a first spacer (1stSp), wherein the second protein includes a second association sequence (2ndA) and a second spacer (2ndSp), wherein the first association sequence and the second association sequence interact with each other with a 1:1 stoichiometry to form a three dimensional scaffold, wherein the first protein is represented by {1stA(1stSp)} x 1stA, where x is ≧2, and the second protein is represented by {2ndA(2ndSp)} 3 2ndA, where y ≧2.
