Original Press Release:

Biocept Launches Liquid Biopsy Kits Intended to Broaden Use of its Proprietary Technology Platform for High Sensitivity Detection of Circulating Tumor DNA

Target Selector™ kits are research-use-only (RUO) and designed to enable laboratories around the world to leverage Biocept's patented assay technology to perform cutting-edge liquid biopsy testing

San Diego, Jan. 28, 2019 /PRNewswire/ -- Biocept, Inc. (NASDAQ: BIOC), a leading commercial provider of liquid biopsy tests designed to provide physicians with clinically actionable information to improve the outcomes of patients diagnosed with cancer, announces the availability of research-use-only (RUO) kits, which are intended to enable molecular laboratories around the world to utilize Biocept's Target Selector™ circulating tumor DNA (ctDNA) assays to perform liquid biopsy testing.  Biocept's Target Selector™ platform is patent protected in the United States and in 10 major international territories. The first available kit is for the high-sensitivity detection of EGFR oncogene mutations, which are among the most frequently evaluated biomarkers for lung cancer. Additional RUO test kits for other oncogene mutations are planned for launch in the future.

Biocept's Target Selector™ ctDNA platform utilizes patented primers, reagents, and methodologies to enrich the specimen for mutations of interest, resulting in very high assay sensitivity and specificity versus methods currently used in most laboratories.

"The launch of our liquid biopsy kit strategy has been a priority for Biocept, and we are excited to now have the ability to leverage the value of our patents as we enable laboratories around the world to utilize our proprietary Target Selector technologies," said Michael Nall, President and CEO of Biocept. "Key objectives for this new business line are to create a leading global brand of research-use-only products, including kits and blood collection tubes, in the liquid biopsy market and to generate additional revenues in addition to those generated by our U.S.-based clinical laboratory business."

About Biocept's Target Selector™ ctDNA Kits

Target Selector liquid biopsy kits are marketed for research-use-only and utilize Biocept's proprietary and patented switch blocker technology to enable industry-leading sensitivity for the detection of mutations/variants of interest in ctDNA (one mutant copy in 10,000 wildtype DNA). These assays can be used on a variety of low-cost analytical platforms including qPCR, Sanger sequencing, microarrays, and mass-spectrometry, in addition to next generation sequencing. Target Selector kits offer high content per assay, which can reduce costs by amplifying multiple mutations/variants in hot-spot regions of interest in a single reaction. All ctDNA tests are quantitative.

The Biocept Target Selector™ EGFR Assay Kit is designed to perform testing for highly informative EGFR mutations that drive lung cancer including Del19, L858R, and T790M.
