[Problem] To provide a signal enhancer that enhances a signal based on reaction between an α1-6 fucose sugar chain and an α1-6 fucose specific lectin bound thereto, a method for using the same, and use of the same. [Solution] A signal enhancer enhances a signal based on reaction between an α1-6 fucose sugar chain and an α1-6 fucose specific lectin bounded thereto, and is characterized by having, as an active ingredient, at least one selected from the group consisting of urea and thiourea. The final concentration of the urea is preferably 1-9 M and the final concentration of the tiourea is 0.1-1.5 M. Since the signal enhancer allows accurate measurement of an α1-6 fucose sugar chain, the signal enhancer is greatly useful in detection and determination of a disease related to an α1-6 fucose sugar chain and in academic study of an α1-6 fucose sugar chain. |
