Mass Spectrometry
The PressureBioSciences Inc.(PBI) focuses on development of specialized products for biological sample preparation which utilize alternating ultra-high hydrostatic pressure–pressure cycling technology(PCT). PCT is a fundament althermo dynamic process which destabilizes molecular interactions by rapidly and repeatedly raising and lowering pressure in the action vessel from atmospheric to levels of up to 45,000 psi.
The Pressure Cycling Technology Sample Preparation System (“PCT SPS”) employs rapid cycles of hydrostatic pressure, between ambient and ultra high levels, to precisely control biomolecular interactions. The PCT SPS can be used to accelerate enzymatic reactions, such as protein digestion with trypsin and other proteolytic enzymes, to prepare samples for analysis by mass spectrometry.
