title: The novel peptide composition of the seeds of Trichosanthes dioica Roxb.
abstract: The seeds of Trichosanthes dioica contain a large amount of peptides in the range of 2-8 kD. These peptides can be resolved in a discontinuous sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) system using Tricine as the trailing ion. The seed proteins contain a number of charge species as determined by isoelectric focusing (IEF) in polyacrylamide gels. The peptides were focused in the basic region as determined by two-dimensional electrophoresis involving IEF and SDS-PAGE. The seed peptides have the unique property of being resistant to the action of silver nitrate, a sensitive reagent commonly used to stain proteins. The seed contains haemagglutinating activity which is inhibited by galactose.
