The CELLSEARCH® product line is owned by Menarini Silicon Biosystems. Menarini Silicon Biosystems is a wholly owned and operated subsidiary of the Menarini Group, a multinational pharmaceutical, biotechnology and diagnostics company headquartered in Florence, Italy. Menarini Silicon Biosystems is based in Bologna, Italy, with U.S. headquarters in Huntingdon Valley, Pennsylvania.

The mission and passion of Menarini Silicon Biosystems is to advance healthcare and personalized medicine by creating technologies and products that help uncover the biological complexities of health and disease at the level of each single cell.

Our highest priority is to improve diagnostic and therapeutic approaches to human health by enabling detection and analysis of important, but rare, cells associated with disease, and to provide researchers and oncologists with access to unparalleled precision in molecular characterization.

Our CELLSEARCH® technology provides a clinically validated test from a simple, minimally invasive liquid biopsy that captures, isolates and enumerates circulating tumor cells (CTCs) for valuable oncologic information to make informed clinical decisions. The CELLSEARCH® CTC product line provides in vitro diagnostic (IVD) applications that are FDA-cleared for predicting overall and progression-free survival in metastatic breast (mBC), prostate (mPC), and colorectal (mCRC) cancers and is the gold standard in CTC technologies.

Menarini Silicon Biosystems also provides end-to-end Research Use Only (RUO) products and workflow solutions with CELLSEARCH® and DEPArray™ technologies for the enumeration, isolation, and molecular characterization of CTCs from a simple blood test in the clinical research setting.
