Biocept, Inc.

San Diego-based Biocept, Inc. (Nasdaq: BIOC) develops and performs diagnostic assays that provide clinically actionable information to improve outcomes for patients with a variety of
cancers.

Biocept’s unique combination of cell-based and cell-free DNA analysis allows us to rapidly detect and monitor certain cancer biomarkers in blood and cerebrospinal fluid (CSF). Our
patented Target Selector™ technology quantitatively analyzes tumor cells for tumor-associated biomarkers, offering high sensitivity and specificity compared with methods currently used by other laboratories.

In addition to our broad portfolio of blood-based liquid biopsy tests, we offer the CNSide™ CSF assay, which addresses an unmet clinical need for patients with cancer that has metastasized to the central nervous system. Between 10% and 30% of patients with cancer will develop brain or spinal cord metastasis. Survival is often low, and few are diagnosed early enough for effective therapeutic intervention. CNSide answers three key questions: Is there a tumor? Is there a
target for treatment? Is there a trend in treatment response?

We offer diagnostic laboratory services for oncologists, pathologists, hospitals, cancer centers, universities, pharmaceutical and clinical researchers, and other healthcare providers. Our CLIA-certified and CAP-accredited laboratory combines a highly trained professional staff with innovative instrumentation for optimal test results and quality control. Biocept works with strategic industry leaders, as well as major cancer centers across the U.S., to further its mission of helping to improve outcomes for cancer patients.

We also are utilizing our molecular diagnostic capabilities to offer nationwide RT-PCR-based COVID-19 testing and services to support public health efforts. Revenue from COVID-19 testing has supported further investment in our core oncology business, positioning the company for long-term success.
