Objectives To identify the components of excretory-secretory proteins(ESPs)of Trichinella spiralis muscle larvae and to analyze proteins related to autoimmune disease. Methods T.spiralis muscle larvae were collected and digested with trypsin,and ESPs were extracted fromT.spiralis muscle larvae.The components of ESPs of T.spiralis were identified with LC-MS/MS after the proteins were separated using sodium dodecyl sulfate polyacrylamide gel electrophoresis(SDS-PAGE).The cellular components,molecular function...
