NEMATODE ANTIGEN TRICHINELLA SPIRALIS

摘要

FIELD: immunology. SUBSTANCE: for preparing substance showing high hemagglutinating activity antigen of nematode Trichinella spiralis (molecular mass is from 16 to 20 kDa) is isolated from larvae or mature trichinas by preparative electrophoresis in 10% polyacrylamide gel in tris-glycine-buffer system (pH = 8.6). Protein fraction elution is carried out with 5 mM solution of NaHCO₃. Prepared substance shows high hemagglutinating activity and can be used in helmintology as diagnostics. EFFECT: improved method of preparing. 1 dwg, 1 tbl
