title: Analysis of lectin properties with membrane ultrafiltration and high-pressure liquid chromatography.
abstract: A convenient method for the analysis of the binding properties of lectin with fluorogenic sugar chains is described. A lectin (concanavalin A or Datura stramonium agglutinin) was mixed with pyridylaminated sugar chains in buffer and the free chains obtained were isolated by membrane ultrafiltration. The amount of free sugar chains in the filtrate was measured by high-pressure liquid chromatography. The binding constants with the sugar chains, reaction kinetics, and other properties of these lectins were easily investigated. The method is simple and could be used to study the characteristics of any lectin in native form.
