IBL-America offers a broad selection of assay kits for cancer and tumor markers. Tumor markers are substances that are produced by cancer or by other cells of the body in response to cancer or certain benign (noncancerous) conditions.
Most tumor markers are made by normal cells as well as by cancer cells; however, they are produced at much higher levels in cancerous conditions. These substances can be found in the blood, urine, stool, tumor tissue, or other tissues or bodily fluids of some patients with cancer. Most tumor markers are proteins. However, more recently, patterns of gene expression and changes to DNA have also begun to be used as tumor markers. Some cancer markers are specific for a single form of cancer, while others can be found in many forms of cancer. Products in this category are for routine diagnostics and research use only.
