Florida International University Receives $349,000 Grant
from the Department of Justice to Improve Rape Case DNA Testing
Using Pressure BioSciences’ Patented Technology

PBI’s PCT System Expected to Play a Critical Role
in Improving Speed and Accuracy of Rape Kit and Other Forensic Lab Tests

South Easton, MA, January 31, 2012 – Florida International University (“FIU”) and Pressure BioSciences, Inc. (NASDAQ: PBIO) (“PBI” and the “Company”) today announced that FIU has been awarded $349,130 from the Office of Justice Programs of the Department of Justice (“DOJ”).  The grant will support the continued development of a faster and more accurate method of processing DNA evidence for rape prosecutions using PBI’s patented Pressure Cycling Technology (“PCT”) Platform.

Dr. Bruce R. McCord, Associate Director of FIU’s International Forensic Research Institute (“IFRI”) and principal investigator of the study, believes the new testing method has the potential to greatly improve the processing of sexual assault evidence, thus helping to reduce the current bottleneck in extracting the DNA evidence contained in rape kits.

News reports point to a current national backlog of more than 400,000 completed rape kits, sitting in storage and waiting processing and analysis. Unfortunately, each warehoused kit may be allowing a rapist to remain free.  New sexual assault cases, estimated at 180,000 annually, tragically add to this backlog.

The DOJ-supported study, entitled “Rapid and selective extraction of DNA from rape kits and other forensic evidence using pressure cycling technology”, is expected to help develop and validate a new DNA extraction technique based on PBI’s PCT platform technology.  Dr. McCord and other forensic researchers at FIU’s IFRI, note that the PBI pressure system (“Barocycler”) provides an exciting new technology that is capable of extracting DNA from rape kits and other samples without the need to first separate sperm from female epithelial cells, a complex and time-consuming procedure.

Dr. Nate Lawrence, VP of Marketing at PBI, said: “Successful completion of the new PCT-based processing method would provide a significant new business channel for PBI, adding to our core strengths in drug discovery and general molecular sample preparation applications.  The forensics market consists of hundreds of labs in the US alone, performing thousands of tests daily.  In addition to instrument sales, we would also expect to supply single-use consumables and buffers that are proprietary to our equipment.”

FIU’s Dr. McCord, a noted expert in forensic DNA research, describes PBI’s PCT technology as having great potential to simplify the complex processing of rape kits. Currently in most forensic labs, the analyst is required to perform a series of tedious manual extractions in order to separate male and female cells collected on swabs from the victim.  With PBI’s PCT System, there is no need to remove female cells prior to analysis.  “The PCT technology permits the user to selectively burst open and extract DNA from the perpetrator’s sperm cells, while leaving the victim’s own cells in the swab sample unbroken.  This unique capability offers great hope for significantly improving rape kit analysis.”

Dr. McCord’s group is scheduled to present an update of their latest PCT studies at the annual meeting of the American Academy of Forensic Sciences, February 20 – 25, 2012, in Atlanta, GA.

Forward-Looking Statements
Statements contained in this press release regarding the Company's intentions, hopes, beliefs, expectations, or predictions of the future are "forward-looking'' statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements include statements regarding the expected advantages of PBI’s PCT product line in processing rape kit samples; the potential for PCT as a tool for the differential extraction of DNA from sperm cells and epithelial cells, without the need for prior separation; that the PCT method has the potential to significantly decrease rape kit processing time, increase throughput, and improve results; that the PCT method could result in an increase in product sales in 2012 and beyond; and the number of unprocessed rape kits and the number of new sexual assault cases each year. These statements are based upon PBI’s current expectations, forecasts, and assumptions that are subject to risks, uncertainties, and other factors that could cause actual outcomes and results to differ materially from those indicated by these forward-looking statements.  These risks, uncertainties, and other factors include, but are not limited to: the results of the DOJ grant may not necessarily confirm previous data on the advantages of using the PCT System in rape kit processing; unforeseen technological difficulties or business issues in the implementation of the PCT method in the processing of rape kits that may impede or prevent the achievement of the expected advantages of the PCT method for such processing; due to unforeseen technical difficulties, or marketing, sales, and distribution difficulties, the PCT method may not be adopted by the forensics  community as an accepted workflow for rape kit sample preparation or the forensics community may not perceive the benefits of PCT for sample preparation; if actual operating costs are higher than anticipated, or revenues from product sales are less than anticipated, the Company may need additional capital prior to March 2012; and if the Company fails to achieve its plan to regain compliance with the NASDAQ Listing Rules for minimum stockholders’ equity and the minimum bid price of $1.00 per share, the Company’s common stock will be delisted from The NASDAQ Capital Market.  Additional risks and uncertainties that could cause actual results to differ materially from those indicated by these forward-looking statements are discussed under the heading "Risk Factors" in the Company's Annual Report on Form 10-K for the year ended December 31, 2010, as amended, and other reports filed by the Company from time to time with the SEC.
