OncoCyte is primarily focused on the development of novel, non-invasive liquid biopsy diagnostic tests for the early detection of cancer. After the distribution of OncoCyte shares, BioTime’s ownership of OncoCyte will be reduced from approximately 76.4% to approximately 58.55%.

Any BioTime shareholder who sells their BioTime shares on or before December 31, 2015 will be selling their entitlement to receive OncoCyte shares to the buyer of their BioTime shares. BioTime shareholders are encouraged to speak to their financial advisor before making any financial decisions.

This press release does not constitute any offer to sell or a solicitation of an offer to buy OncoCyte common stock.

About OncoCyte Corporation

OncoCyte is primarily focused on the development of novel, non-invasive liquid biopsy diagnostic tests for the early detection of cancer to improve health outcomes through early diagnoses, to reduce the cost of care through the avoidance of more costly diagnostic procedures, including invasive biopsy and cystoscopic procedures, and to improve the quality of life for cancer patients.

While current biopsy tests use invasive surgical procedures to provide tissue samples in order to determine if a tumor is benign or malignant, OncoCyte is developing a next generation of diagnostic tests that will be liquid biopsies using blood or urine samples. OncoCyte’s initial liquid biopsy tests under development are intended to be confirmatory diagnostics for detecting lung, bladder and breast cancer. OncoCyte’s diagnostic tests are being developed using proprietary sets of genetic and protein markers broadly expressed in numerous types of cancer.

OncoCyte is a subsidiary of BioTime, Inc., a clinical-stage biotechnology company that is a pioneer in regenerative medicine. BioTime and its subsidiaries are leveraging their industry-leading pluripotent stem cell technology and a broad intellectual property portfolio to facilitate the development and use of cell-based therapies for major diseases and degenerative conditions for which there presently are no cures.
