Tetramer Assay for Measuring T-Cell Responses
Serametrix T-cell Profiling measures T-cell activation to tumor antigens. Using patented tetramer technologies and reagents from the Ludwig Institute for Cancer Research (LICR), this assay measures a patient’s cellular immune response to specific panels of tumor antigens and can reveal the relationship between T-cell activation and clinical outcome to immunotherapy (1,2).
- Breast cancer
- Colorectal cancer
- Non-small cell lung cancer
- Pancreatic cancer
- Prostate cancer
- Renal cell carcinoma
- Ovarian cancer
For most disease panels it is possible to measure not only CD8+ cytotoxic T-cell responses but also CD4+ helper T-cells. In addition, the range of patient haplotypes that can be measured is increasing, with almost complete patient coverage for the leading cancer types.
