A novel recombinant bioadhesive designed from the non-repeating region of Perna viridis foot protein-1

► Recombinant R-240 and C-237 derived from Pvfp-1 were expressed and purified. ► Both proteins has good adhesion and coating abilities, especially the modified-C-237. ► Both proteins were non-toxic to cells. ► C-237 exhibited better cell-adhesion and spreading ability especially on PTFE surface. ► The adhesion mechanism for C-237 might be collagen-adhesion as well as DOPA-adhesion.
