. Although recombinant fp-151-RGD
maintained the advantages associated with fp-151, such as a high production yield in Escherichia coli and simple purification, it showed
superior spreading ability, which is important for cell proliferation under serum-free conditions, as well as better cell-adhesion ability
compared with other commercially produced cell-adhesion materials such as poly-L-lysine (PLL) and the naturally extracted MAP
mixture Cell-Tak.
