The production and properties of an antiserum to potato (Solanum tuberosum) lectin

Abstract

Precipitation of potato (Solanum tuberosum) lectin by antisera was not affected by treatments that abolish lectin activity. An antiserum precipitated glycosylated derivatives of the lectin but not a deglycosylated peptide. The haemagglutination inhibition titre of this antiserum was not affected by removing anti-glycopeptide antibodies. This evidence suggests that the antiserum contains two populations of antibodies, specific for different domains of the lectin.
