Observation and release kinetics of mimetic peptides from Chi/PDA-Ps conduits.

(A) Schematic diagram of Chi/PDA-Ps conduit preparation. (B) Side and cross-section view after functional peptides were immobilized on Chi/PDA conduits. RGI was modified with FITC (green fluorescence) and KLT was modified with TAMRA (orange fluorescence). (C) Release curves of RGI and KLT from Chi/PDA-Ps conduits. Data are expressed as mean ± SEM. The experiments were repeated three times. Chi/PDA: Polydopamine-coated chitin conduits; Chi/PDA-Ps: polydopamine-coated chitin conduits loaded with functional peptides; FITC: fluorescein isothiocyanate isomer; RGI: RGIDKRHWNSQ; KLT: KLTWQELYQLKYKGI; TAMRA: carboxytetramethylrhodamine.
