[Study of peptide content of antibacterial fractions by liquid chromatography and mass spectrometry].

The fractions containing antimicrobic peptides have been purified from a haemolymph of caterpillars Galleria mellonella by chromatographic methods and studied by mass spectrometry.

[Comparison of the results of research of hemolymph immunized and nonimmunized of larvae of Galleria mellonella].

This work deals with the antibacterial activity of larvae of Galleria mellonella. Protein fractions with antibacterial activity have been purified from hemolymph by ion-exchange chromatography and gel-electrophoresis. The mass-spectrometric analysis of fractions showed the presence of a peptide of 5627 Da.
