This document relates to methods and materials for detecting premalignant and malignant neoplasms. For example, methods and materials for determining whether or not a stool sample from a mammal contains nucleic acid markers or polypeptide markers of a neoplasm are provided.

Detecting neoplasm

The present invention provides methods and materials related to the detection of colorectal neoplasm-specific markers in or associated with a subject's stool sample. In particular, the present invention provides methods and materials for identifying mammals having a colorectal neoplasm by detecting the presence of exfoliated epithelial markers (e.g., human DNA, tumor assoicated gene alterations, tumor associated proteins) and blood markers (e.g., homoglobin, serum proteins) in a stool sample obtained from the mammal.

Methods for detecting colorectal cancer using a DNA marker of exfoliated epithelia and a fecal blood marker

This document provides methods and materials involved in removing polypeptides (e.g., high abundance polypeptides) from stool samples. For example, methods and materials for preparing a stool sample for detecting polypeptides of low abundance are provided. For example, this document provides methods and materials for depleting abundant polypeptides common to stool from normal, healthy humans from a stool sample. Such depleted stool samples can be used to detect polypeptides of interest such as low abundance polypeptides or neoplasm-specific polypeptide markers that can be present in a mammal suffering from a disease such as cancer.

Removing polypeptides from stool

This document provides methods and materials involved in collecting and processing complex macromolecular mixtures (e.g., stool samples). For example, stool collection devices, buffers for stabilizing nucleic acid and polypeptides present in stool, and kits for using sequence-specific capture probes (e.g., nucleic acid sequences designed to hybridize with particular target nucleic acids) to capture target nucleic acids directly from complex macromolecular mixtures (e.g., stool samples) without the need to perform prior steps to enrich, isolate, or purify the nucleic acid component are provided.
