Method for detecting cancer, and antibody capable of recognizing pancreatic ribonuclease 1

Abstract

Pancreatic cancer can be detected using a monoclonal antibody which binds to pancreatic RNase 1 when a site in pancreatic RNase 1 capable of being modified with an N-glycan chain is not linked to a glycan chain, but which does not bind to pancreatic RNase 1 when an N-glycan chain is linked to the site. Also provided is a monoclonal antibody which can bind to pancreatic RNase 1 simultaneously with the binding of the aforementioned antibody to pancreatic RNase 1, and determining the ratio of A to B using the antibodies, wherein A represents the amount of the site located in the pancreatic RNase 1 capable of being modified with an N-glycan chain, wherein an N-glycan chain is linked or not linked to the site; and B represents the amount of the site located in the pancreatic RNase 1 capable of being modified with an N-glycan chain.
