摘要:
The venom of Lycosoidea spiders is a complex multicomponent mixture of neurotoxic peptides (main components) and antimicrobial peptides (AMPs) as minor components. In this study, we described the high-throughput identification and analysis of AMPs from Lycosa sinensis venom (named LS-AMPs) using a combination strategy that includes the following three different analysis approaches: (i) peptidomic analysis, namely reversed-phase high-performance liquid chromatography (RP-HPLC) separation plus top-down sequencing by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MS...
