<p>To provide a method of accurately detecting pathological haptoglobin using a lectin having strong affinity and high specificity for fucose. The method of the present invention for detecting pancreatic cancer is characterized in that a fucose ±1†’6 specific lectin is allowed to act on pathological haptoglobin contained in a sample obtained from a living body, said lectin: (1) being extractede from basidiomycetes, (2) having a molecular weight of 4,000 to 40,000 as determined by the SDS polyacrylamide gel electrophoresis, and (3) having affinity for a fucose ±1†’6 sugar chain with a binding constant of 1.0 × 10 4 M -1 or more at 25°C.</p> |
