(A) Schematic of the protein polymer hydrogel formation by tissue transglutaminase enzymatic crosslinking. (B&C) Photograph of the precursor solution before and after enzymatic gelation with tTG. (D) Photograph of a transparent hydrogel crosslinked by hTG. Gels were composed of K830/BQ6 (8 wt% protein polymers and 0.26 units of tTG or 20μM hTG).
