Application: Thermo Electron offers the FRENCH Press and two models of FRENCH Pressure Cells for the disintegration of chloroplast materials, blood cells, unicellular organisms, homogenates of animal tissue and other biological particles. The pressure cell disrupts the cellular walls of a sample while leaving the cell nucleus undisturbed. This technique results in more uniform and complete disruption. The FRENCH Pressure Cell delivers higher pressures than bombs or decompression systems, without pre-treating the sample. Cells are lysed by forcing the cell or tissue suspension through a narrow space, thereby shearing the cell membraneøs.A French press consists of a piston that is used to apply high pressure to a sample volume of 40 to 250 ml, forcing it through a tiny hole in the press. It can reach pressures of 20,000-40,000 pounds per square inch (psi).

Application: The Beckman HPLC has solvent delivery modules that are built with a rapid fill pump design that produce smooth flow from microbore to semi-preparative flow rates and thee high-pressure mixing design eliminates the need for constant helium sparging or degassing. The pumps are combined with high-sensitivity UV/VIS and diode array detectors and autosamplers.

Preparative HPLC refers to the process of isolation and purification of compounds. Important is the degree of solute purity and the throughput, which is the amount of compound produced per unit time. This differs from analytical HPLC, where the focus is to obtain information about the sample compound. Chemical Separations can be accomplished using HPLC by utilizing the fact that certain compounds have different migration rates given a particular column and mobile phase. Each compound should have a characteristic peak under certain chromatographic conditions. Depending on what needs to be separated and how closely related the samples are, the chromatographer may choose the conditions, such as the proper mobile phase, to allow adequate separation in order to collect or extract the desired compound as it elutes from the stationary phase. With these characteristic peaks, identification of compounds can be done. HPLC also allows for quantification of compounds by determining the unknown concentration of a compound in a known solution.

Application: Sublimation occurs when a frozen sample goes directly to the gaseous phase without passing through the liquid phase. As the ice sublimates, it leaves voids in the dry residual material making it easy to rehydrate. Freeze drying samples stabilizes them for storage, preservation, or shipping . Many times, drying causes damage and some loss of cellular or protein activity. Lyophilization is a method of sample preservation that significantly reduces damage to biological samples. Substances that are not damaged by freezing can usually be lyophilized so that refrigerated storage is unnecessary. Important exceptions are mammalian cells, nearly all of which are destroyed by lyophilization. However, many microorganisms and proteins survive lyophilization well, and it is a preferred method of drying vaccines, pharmaceuticals, blood fractions, and other laboratory samples.

Application: Sublimation occurs when a frozen sample goes directly to the gaseous phase without passing through the liquid phase. As the ice sublimates, it leaves voids in the dry residual material making it easy to rehydrate. Freeze drying samples stabilizes them for storage, preservation, or shipping . Many times, drying causes damage and some loss of cellular or protein activity. Lyophilization is a method of sample preservation that significantly reduces damage to biological samples. Substances that are not damaged by freezing can usually be lyophilized so that refrigerated storage is unnecessary. Important exceptions are mammalian cells, nearly all of which are destroyed by lyophilization. However, many microorganisms and proteins survive lyophilization well, and it is a preferred method of drying vaccines, pharmaceuticals, blood fractions, and other laboratory samples. Some specialist food products are also lyophilized.

Application: DNA Microarrays and Proteomic Technologies allow scientists to detect genes or proteins that are coregulated and whose patterns of change correlate with something important such as a disease state. However there is no assurance that these changes are really significant to the cell. Phenotype MicroArrays are a complementary technology providing the needed information at the cellular level ... and much more. After a genetic change or exposure to a drug lead, the researcher can directly evaluate the cellular response to that change. Phenotype MicroArrays can monitor, either directly or indirectly, most known aspects of cell function. The range of phenotypes includes:

• Cell surface structure and transport functions
• Catabolism of carbon, nitrogen, phosphorus, and sulfur
• Biosynthesis of small molecules
• Synthesis and function of macromolecules and cellular machinery
• Cellular respiratory functions
• Stress and repair functions
• Other cellular properties

Application: Some of the separation Methods used in preparative ultracentrifugation:

Differential centrifugation: pelleting. Start with a uniform mixture of sample – molecules or organelles in buffer. Centrifuge to obtain pellet of heavier molecules, and supernatant.

Density gradient centrifugation: Rate zonal (also termed sedimentation velocity, zone centrifugation). Use a continuous density gradient of solvent such as sucrose. Density increases toward the bottom of tube. Sample is layered on top. Centrifuge until molecules form discrete bands depending upon their sedimentation values. Generally stop the run before any of the molecules reaches the bottom. 100% separation is possible with a small sample. Separates molecules based on size (MW). Used to separate various types of macromolecules – mixture of proteins; different types of RNA; separate DNA from RNA, or proteins; ribosomal subunits; polyribosomes.

Density gradient centrifugation: Isopycnic centrifugation (also termed sedimentation equilibrium centrifugation). Mix gradient material (such as cesium chloride- CsCl) with sample molecules. During the centrifugation, the CsCl generates a gradient (“self-generating gradient”), and the molecules move to the position in the gradient where their density is the same as the gradient material. Requires long centrifugation time to form a gradient (36-48 hrs). Separates molecules based on their density – may have the same size. Often used to separate various types of DNA – circular vs linear, double stranded vs single stranded, DNA from RNA (RNA pellets), highly repetitive DNA (satellite DNA) from other DNA in the cell, can be used for separation of lipoproteins and cell organelles.
