PROBLEM TO BE SOLVED: To provide a method for specifically detecting a tumor-associated antigen derived from a glycoprotein class called N-CAM in a human body fluid. A method for qualitatively or quantitatively detecting a tumor-associated antigen derived from a glycoprotein class called N-CAM in human body fluid, comprising sialic acid, polysialic acid or α- (2,8)- A specific binding partner for linked N-acetylneuraminic acid and other sialic acid, polysialic acid or other on the tumor-associated antigen but not for α- (2,8) -linked N-acetylneuraminic acid The above method comprising using in combination with a second specific binding partner that recognizes the epitope. |
