Patent ID: 8735168

Claim:
A method for preparing a human stool sample for detecting polypeptide, wherein said method comprises reducing the concentration of two or more polypeptides known to be in high abundance within a human stool sample, wherein said two or more polypeptides are selected from the group consisting of pancreatic alpha-amylase, alpha-amylase 2B, salivary alpha-amylase, Ig kappa chain C region, carboxypeptidase A1, elastase-2A, maltase-glucoamylase intestinal, intestinal alkaline phosphatase, and dipeptidyl peptidase, wherein an antibody conjugated resin is used to reduce the concentration of pancreatic alpha-amylase, alpha-amylase 2B, salivary alpha-amylase, Ig kappa chain C region, carboxypeptidase A1, elastase-2A, maltase-glucoamylase intestinal, intestinal alkaline phosphatase, and dipeptidyl peptidase 4.
