Tumor Markers

Tumor marker antibodies for use in diagnostic assays to detect or monitor cancer

Cancer is the second most common cause of death after cardiovascular disease and there are certain markers which can be used to indicate that a malignancy is present, known as tumor markers or tumor antigens.

The ideal tumor marker would be one that is secreted only from malignant cells however no such tumor markers exist with 100% specificity or sensitivity. High levels of certain markers can only indicate the presence of different forms of cancer. Most tumor markers simply show a correlation with tumor progression. These tumor markers can also be used to monitor disease progression once it has been detected and diagnosed by other methods.

Tumor markers can be classified in two groups: cancer-specific markers and tissue-specific markers. Cancer-specific markers are related to the presence of certain cancerous tissue. Tissue-specific markers are substances that are not related directly to the tumor, but elevated levels may point to a malignancy in the tissue.

Our range of tumor markers includes the following antibodies, all available in bulk for diagnostic assays.

Prostate specific antigen (PSA) antibodies

Carcinoembryonic antigen (CEA) antibodies
