    ABSTRACT: Antimicrobial peptides (AMPs) are cationic molecules that are good leads for new antiinfective drugs. To obtain sufficient amounts, recombinant AMPs are generally produced as fusion proteins in Escherichia coli. Fusion partners facilitate purification of recombinant proteins. Fusion proteins are then cleaved by specific proteases, and cationic peptides are purified by size exclusion chromatography or ion exchange chromatography, neither of which is easily applicable to small volumes of diluted peptide samples. We developed a small-scale system that is easily adaptable for high-throughput screening and uses carboxyl magnetic beads to purify a cationic peptide from its fusion partner.
