The issuance of this patent provides additional protection in China to Biocept's key technologies that are core to its CTC platform. This staining method is a component of the Company's proprietary Cell Enrichment and Extraction (CEE) platform, providing for the high-efficiency capture, visualization, and microscopic analysis of targeted cells that are obtained from a patient's blood sample and used by physicians to aid in medical decision making.

Lyle Arnold, Ph.D., Chief Scientific Officer at Biocept, said, "The issuance of this patent further strengthens our patent protection in China covering our core technologies that are central to Biocept's platform for the transport, capture, enrichment, identification and analysis of CTCs from blood samples and other biological sample types."
