SOUTH EASTON, Mass., July 7, 2015 /PRNewswire/ -- Pressure BioSciences, Inc. (OTCQB: PBIO) ("PBI" and the "Company"), a leader in the development and sale of broadly enabling, pressure cycling technology ("PCT")-based sample preparation solutions to the worldwide life sciences industry, today announced the development of a two-step, PCT-enhanced method for the selective differential extraction of male or female DNA from mixtures of sperm and vaginal epithelial cells recovered from cotton swabs. The results of the study were recently published in Analytical and Bioanalytical Chemistry, a leading peer-reviewed scientific journal. The authors of the paper were Dr. Deepthi V. Nori and Dr. Bruce R. McCord of the Department of Chemistry, Florida International University ("FIU").
For years, biological samples for forensic analysis (e.g., body fluids) have been collected using cotton swabs. Unfortunately, sample recovery (e.g., cells, DNA) from these swabs can be cumbersome, time-consuming, difficult, and expensive. Often the biological sample is trapped in the swab's cotton fibers, resulting in a loss of precious evidence. Over the years, there have been many attempts to develop new methods to improve the speed and quality and to reduce the cost of recovering biological samples from cotton swabs, including the recovery of DNA from swabs taken after a sexual assault.
Dr. McCord, Associate Director of FIU's International Forensic Research Institute ("IFRI") and principal investigator of the study, said: "Our study presents a novel technique to extract biological fluids from cotton swabs with high recovery, using PCT combined with alkaline lysis. This new method has shown decreased processing times and higher yields while using inexpensive reagents on a semi-automated platform. Although there is still work to be done, results to date indicate this PCT-based technique is a promising new method for extraction of DNA from forensic evidentiary materials, including rape kits."
News reports point to a current national backlog of more than 400,000 untested rape kits, sitting in storage and awaiting processing and analysis. Unfortunately, each untested kit may be allowing a rapist to remain free. New sexual assault cases, estimated at 180,000 annually, tragically add to this backlog.
Mr. Richard T. Schumacher, President and CEO of PBI, said: "We believe this novel, PCT-dependent method represents a potential breakthrough in the recovery of high quality DNA from cotton swabs. Next steps will be to optimize and streamline the method. To that end, we have begun discussions to formalize the relationship between PBI and Dr. McCord/FIU into a mutually-beneficial collaboration agreement. We believe that by combining capabilities, knowledge, and our shared interest in an effective outcome, we can more efficiently move this method down the path to potential commercialization."
Mr. Schumacher continued: "Future commercialization of this novel, PCT-based method could potentially provide significant new business channels for PBI in important forensic applications, such as touch DNA and rape kit testing. We believe the forensics market consists of hundreds of labs in the US, performing thousands of tests on a routine basis. Thus, in addition to instrument sales, we also see the potential for single-use consumables and other reagents that are proprietary to our PCT platform."

About Pressure BioSciences, Inc.
Pressure BioSciences, Inc. ("PBI") (OTCQB: PBIO) develops, markets, and sells proprietary laboratory instrumentation and associated consumables to the estimated $6 billion life sciences sample preparation market. Our products are based on the unique properties of both constant (i.e., static) and alternating (i.e., pressure cycling technology, or PCT) hydrostatic pressure. PCT is a patented enabling technology platform that uses alternating cycles of hydrostatic pressure between ambient and ultra-high levels to safely and reproducibly control bio-molecular interactions. To date, we have installed over 250 PCT systems in approximately 160 sites worldwide. There are over 100 publications citing the advantages of the PCT platform over competitive methods, many from key opinion leaders. Our primary application development and sales efforts are in the biomarker discovery and forensics areas. Customers also use our products in other areas, such as drug discovery & design, bio-therapeutics characterization, soil & plant biology, vaccine development, histology, and forensic applications.
