A galactose-specific lectin has been purified from the seeds of Trichosanthes cordata by affinity chromatography on crosslinked guar gum. The affinity-eluted lectin could be resolved into two isolectins, TCA-I and TCA-II by ion-exchange chromatography on DEAE cellulose. The molecular weights of the

A prominent lectin in the root tubers of Trichosanthes japonica was purified by affinity chromatography on a porcine stomach mucin-Sepharose column and termed TJA-II. The molecular mass of the native lectin was determined to be 64 kDa by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and

Purification and characterization of a Neu5Ac alpha 2-->6Gal beta 1-->4GlcNAc and HSO3(-)-->6Gal beta 1-->GlcNAc specific lectin in tuberous roots of Trichosanthes japonica.
