Purification and identification of antibacterial peptide Kiadin. A Supernatants and precipitates of acid cleavage products of DAMP4–DPS–Kiadin treated with isoelectric precipitation (IP) and freeze-drying (FD), respectively, which were showed by Tricine–SDS–PAGE with silver staining. B Characterization of purified PS–Kiadin–HH determined by RP‑HPLC. C Mass spectra of purified PS–Kiadin–HH determined by electrospray ionization mass spectrometry
