SOUTH EASTON, Mass., June 9 /PRNewswire-FirstCall/ -- Pressure BioSciences, Inc. (Nasdaq: PBIO) ("PBI") today announced that scientists from Pacific Northwest National Laboratories (PNNL), the Harvard School of Public Health (HSPH), the Commonwealth of Virginia (CoVA) Laboratory, and the Food and Drug Administration (FDA) presented data generated through the use the Company's patented pressure cycling technology (PCT) at last week's (June 1-5) American Society for Mass Spectrometry's 56th Annual Conference in Denver, Colorado. These included three poster presentations and an oral presentation relating to research on biodefense and on improving the preparation of samples for studies of proteins.

According to Dr. Daniel Lopez Ferrer and his colleagues at PNNL, one of the most time-consuming steps in studying proteins is the long incubation period (6-12 hours) required to break (digest) proteins down into their building blocks (peptides), often done with the enzyme trypsin. In their poster presentation, the authors discussed the effect of high pressure (up to 35,000 psi) -- with pressure cycling technology (PCT) and with an on-line high pressure system -- on the tryptic digestion of proteins. They reported that complete digestion of proteins could be achieved in just 60 seconds. The researchers further reported that high pressure digestion "resulted in a noticeable improvement in the number of (peptide) identifications." They concluded that an on-line high pressure system "looked promising for ultra- high throughput applications, i.e., proteomics on the fly."
