Tumor Biomarkers

Screening for tumors based on proteins found in body fluids like plasma, urine, cells/ tissues is another approach to diagnose the presence of cancer and monitor its progression. These marker proteins are expressed at physiological levels in normal cells; however the levels increase by several folds in a cancer milieu. At this point there are ~20 different generic or specific tumor markers that are used for the diagnosis of cancer.

Our growing portfolio of research related products for specific tumor markers would enable researchers to understand the basic biology related to tumor biomarkers related to specific types of cancers
