The issuance of this patent expands Biocept’s intellectual property protection for the detection of rare mutations, including cancer biomarkers found in tissue, blood and cerebrospinal fluid. This is the second issued patent for the Primer-Switch technology, and is another step in Biocept’s pursuit of worldwide patent protection for this technology. The Primer-Switch technology provides another method for specifically enriching patient specimens for oncogene mutations of interest. Additionally, the Primer-Switch technology can be used to enhance the performance and specificity of the PCR method, which is the most widely used amplification approach used in diagnostic assays.

"Our Primer-Switch methodology has the potential to find rare mutations in PCR reactions, especially where the detection of rare genetic events is needed, or in cases where more precise PCR amplification reactions are desired or required," said Michael Nall, Biocept’s President and CEO. "This technology builds upon our ability to detect rare genetic events in addition to our Switch-Blocker technology, which we routinely use in our ctDNA Target Selector assays. This is another tool in our toolkit for methods to inform on biomarkers found in tissue, blood and cerebrospinal fluid to aid physician decision making in the treatment of their patients with cancer."
