Abstract

This invention provides reagents and kits that enable highly sensitive and accurate measurement of DUPAN-2 antigen in a sample. [Solution] A reagent for measuring DUPAN-2 antigen in a sample, comprising an insoluble carrier and an antibody or a fragment thereof that binds to the DUPAN-2 antigen, wherein when DUPAN-2 antigen derived from ascites fluid and DUPAN-2 antigen derived from human pancreatic cancer cell HPAF are measured, the following formula (X) is satisfied: 0.8 ≤ (B) / (A) ≤ 1.2(X) (wherein (A) is the measured value of DUPAN-2 antigen derived from ascites fluid, and (B) is the measured value of DUPAN-2 antigen derived from human pancreatic cancer cell HPAF, and the antigen concentration ratio of DUPAN-2 antigen derived from ascites fluid to DUPAN-2 antigen derived from human pancreatic cancer cell HPAF is 1:1.)
