Detect early warning signs of colon cancer with GlycoKnow Colon

GlycoKnow Colon is a blood-based laboratory-developed test (LDT) designed to assess the presence of adenomas with high-grade dysplasia or colorectal cancer by harnessing the power of the immune system.

Colorectal Cancer Screening Rates Remain Low1

Colorectal cancer (CRC) is the second leading cause of cancer death in the United States, leading to over 50,000 deaths annually. With appropriate and timely screening, CRC is highly preventable and treatable, and early detection is critical to improving patient outcomes.

Unfortunately, screening rates remain below national targets, exacerbated by the lack of convenient and effective options for patients.

The GlycoKnow Colon blood test makes it easy to be screened

Once available, a single blood draw will be able to put patients on the path to receiving care before a tumor has developed, and when intervention is most optimal.

Advancing precision medicine with glycoproteomics

Proteins undergo a variety of post-translational modifications. Glycosylation, the enzymatic attachment of sugar structures, is one of the most abundant and critical of these modifications, impacting more than 70% of proteins, altering their function and structure2. Protein glycosylation is a critical feature associated with tumor development, including colorectal cancer.

GlycoKnow Colon unlocks the glycoproteome using novel high-throughput mass spectrometry technologies paired with AI-powered data processing and machine learning. It measures both the abundance of and the variation in glycosylation profiles of glycoproteins in serum isolated from blood, providing an unprecedented view into the systemic response of the body to the progression of colorectal cancer.

GlycoKnow Colon measures the immune response of early stage disease

GlycoKnow Colon monitors the body’s response to disease progression, enabling pre-cancer detection. Other tests rely on material shed by the tumor, missing early stage.
