Trade Secrets

  • Fucosylated biomarker assay manufacturing technology
  • Fucosylated biomarker assay methods

KEY FEATURES

• Exploits unique disease signal chemistry (glycoprotein fucosylation) present in liver cancers and fibrosis-cirrhosis but absent in healthy individualsIncorporated into highly promising biomarker panels

• Focused on the detection of potentially curable early-stage disease

• May outperform currently available serum biomarkers, such as AFP

• Targeting the worldwide liver cancer threat that kills more than 700,000 people annually and is the fastest growing cause of cancer death in the US

GLYCOTEST PRESENTATION

A New Paradigm for Early Diagnosis and Surveillance For Liver Cancer

GLYCOTEST TECHNOLOGY

Glycotest blood tests are being developed to provide information on the likelihood of serious liver disease like cancer or fibrosis-cirrhosis by employing technology designed to measure two kinds of disease signals:
• The amount of the monosaccharide fucose that appears abnormally on certain serum glycoproteins—to indicate likelihood of disease.
• The pattern of glycoproteins that is abnormally fucosylated—to monitor specific diseases like HCC, CCA or fibrosis-cirrhosis.
