Transform Any Cell Type

The biolistic PDS-1000/He instrument is capable of accelerating sub cellular-sized tungsten or gold microprojectiles coated with DNA over a range of velocities and target distances necessary to optimally transform many different cell types. Particle delivery with the PDS-1000/He system is a convenient method for transforming intact cells in culture since very little pre- or post bombardment manipulation is necessary, and sample containment within the evacuated bombardment chamber offers maximum control.Biolistic bombardment allows transformation of animal cells with unique growth requirements that are not amenable to gene transfer using any other method. Reports describing how to transform cultured mammalian cells with the PDS-1000/He device (see References) show improved transient transformation of a variety of sensitive mammalian cells that are poorly transformed by chemicals, lipofection, or even electroporation. In addition, you can use less DNA and fewer cells for either transient or stable transformation with the biolistic particle delivery system. This technique is much easier and faster than the tedious task of microinjecting embryos. How the Unit WorksThe helium pressure and vacuum circuits in the PDS-1000/He system effectively accelerate the microcarriers into the target cells: After all the materials are in place, the chamber door is closed and a vacuum is applied. The vacuum reduces the frictional drag on the DNA-coated microcarriers and provides a safety interlock; the instrument cannot be activated unless a vacuum is drawn.Activating the fire switch allows helium to flow into the gas acceleration tube at a rate regulated by the helium-metering valve and monitored by the helium pressure gauge. The gas is held until the burst pressure of the rupture disk is reached. This generates a helium shock wave into the bombardment chamber.The shock wave hits the microcarrier launch assembly and propels a plastic macrocarrier holding DNA-coated microcarriers toward the target cells. A stopping screen placed between the macrocarrier assembly and the cells retains the plastic disk, while allowing the coated microprojectiles to pass through and transform the target cells.Bombardment ParametersWe recommend these settings for bombardment of a variety of cell types. Many factors affect bombardment efficiency, but most users will find it sufficient to optimize the major variables individually, then test their interactions on a limited scale.

Circular Dichroism Spectrophotometer

The Aviv Model 215 Circular Dichroism Spectrometer

Circular dichroism spectroscopy measures physical phenomena wherein molecules absorb to different extents circularly polarized light. Differences in the absorbance are directly related to the optical activity of chiral molecules.  
Circular dichroism is an essential tool of measuring secondary structure of proteins, ligand binding and macromolecular association.  Deconvolution of the spectra can give a quantitive measure of protein secondary structure.
The Aviv model 215 Circular Dichroism Spectrometer records circular dichroism as a function of wavelength, time, temperature, pH and concentration using a double monochromator containing two UV grade prisms as dispersing elements. Focusing optics allows use of micro cells. A 50 Khz photoelastic modulator produces right and left circularly polarized light.

PAM 2000
"PAM-Fluorometer Family" employs the so-called Pulse-Amplitude-Modulation (PAM) measuring principle, which is unique in providing a highly selective measure of the relative chlorophyll fluorescence quantum yield. In conjunction with the so-called "saturation pulse method" of fluorescence quenching analysis PAM-2000 -Fluorometers allow rapid assessment of photosynthetic energy conversion. Measuring principle and quenching analysis
   The Portable Chlorophyll Fluorometer PAM-2000 has been developed on the basis of the well-known PAM Fluorometer. The patented pulse amplitude modulation (PAM) measuring principle is used to measure the fluorescence yield with high
Sensitivity and selectivity, whereby even strong unmodulated light (e. g. full sunlight and saturation pulses with 10000 Ámol quanta ms) causes no disturbing effects.
The intensity of the measuring light is sufficiently low that it has no effect on the Photosynthesis State and the fluorescence yield. In addition to the current fluorescence yield (Ft, in continuous light) and the maximum yield (Fm', in the saturation pulse) it is also possible to determine the minimum yield (Fo', in the quasi-dark state). This information is automatically evaluated by the data acquisition system integrated in the PAM-2000 Fluorometer such that the quenching coefficients (qP and qN), the effective quantum yield (F/Fm') and the apparent electron transport rate (PAR x F/Fm') are obtained within seconds following each saturation pulse

 Detector-DTGS (KBr Window): deuterated triglycine sulfate. A very sensitive detector for mid infrared range measurement. Most routine scanning instruments feature the more expensive and more sensitive DTGS detector, which is one or two orders of magnitude more sensitive than lithium tantalate, depending upon implementation. One drawback of the DTGS detector in a process environment is that it stops functioning as a detector at temperatures higher than 41 degrees C; the detector depolarizes above this temperature.

 href="">PIXImus Academic and pharmaceutical researchers commonly use the mouse for investigations of genetics, cellular physiology, and of agents affecting bone or soft-tissue composition. Bone densitometry and body composition measurement using dual-energy x-ray absorptiometry (DEXA), eliminate the need for destructive chemical analysis - a time- and labor-consuming process that requires days or weeks to complete. Bone densitometry allows the researcher the opportunity to make multiple measurements in-situ during the life of the animal. Unfortunately, DEXA densitometers using rectilinear scanning require as much as 30 minutes for a total body acquisition with relatively poor precision (>5%) and spatial resolution (>0.5mm). The long process requires careful sedation techniques and often endangers animal safety. The PIXImus densitometer provides bone mineral and body composition results from total body imaging in under 5 minutes. Fast imaging allows use of milder sedation that is safer on animals.The PIXImus allows accurate and precise measurement of bone and tissue for small animals 10-50 g (e.g.,mice, lemmings). This measured bone exhibits excellent correlation to total ashed weight (r=0.99). PIXImus uses a lower x-ray energy than that used for peripheral densitometry in humans in order to achieve contrast in the extremely low density bone. Excellent precision of BMD and %Fat makes PIXImus ideal for longitudinal studies. The standard total body focuses on the active bone area in the subcranial region. There are manual ROI's for selected regions within the total body image, such as spine and femur. /P>< /FONT>

X-ray Diffraction


The possibility of using powder diffraction methods to study materials was recognized shortly after the discovery of X-ray diffraction by von LaŘe and Knipping in 1910. In particular, the construction of a simple powder diffractometer was described by Hull in 1917, and the instrument was used to obtain patterns from a number of simple materials such as diamond, graphite and iron. Within a few years, many others, including the Braggs and Pauling, had exploited the powder method to study a wide range of materials, including metals, minerals, and simple organic solids .

    Optilab Refractive Index Detector

    The Optilab« rEX (refractometer with EXtended range) is an Refractive Index detector with 256 times the detection power and up to 50 times the dynamic range of every RI detector in existence today. Using a combination of cutting-edge semiconductor photodiode technology and proprietary computer algorithms, the rEX presents a host of instrument firsts.
    For example, there are no range or gain settings. The full range of instrument detection is always present, and the full sensitivity exists over the entire range. 
    The rEX also has a flow cell with a total volume of only 7.4 uL -- 25% less than the leading refractometers available today. This translates into minimized band broadening and better temperature stability.
    The Optilab« rEX can also do something no other on-line Refractive Index detector can: it can measure the absolute refractive index of a solution. In addition, it can measure the dn/dc of a solvent at the same wavelength of light as the light scattering instrument. And just to make sure it can't be matched, you can replace the light source in the rEX for other wavelengths (e.g. 690, 633, 488, etc.)!
    The new Optilab« rEX shares the ability its predecessor (the Optilab« DSP) to go to below ambient temperatures as easily as above ambient. No hassle temperature control can be programmed down to 4░C or as high as 50░C. Compatible with all HPLC systems.

    ImageQuant 350
    ImageQuant 350 allows high-resolution scans of monochromatic fluorescence gels, Coomassie Blue-stained gels, and other colorimetric detection methods.

    ImageQuantT 350 is a high-performance 16-bit cooled CCD camera-based system designed for a wide range of monochromatic imaging applications. ImageQuant 350 is well-suited for quantitative analysis of Western blots. The system is also fully capable of imaging monochromatic fluorescent gels and membranes, CoomassieT Blue-stained gels, and other colorimetric detection methods. Cultures and microplate-based assays can also be imaged. Whereas film is valuable and convenient for certain applications, ImageQuant 350 supports a more quantitative approach for a broader range of applications without compromising sensitivity, resolution, or simplicity of operation. Most commands are performed by pushing a single button, thereby supporting many different applications in a day.

    The ImageQuant 350 is a compact, easily installed system, designed for easy exchange of cameras, lenses, and filters. The standard system includes one manual fixed lens and one manual zoom lens, and the motorized system includes one motorized fixed lens and one manual zoom lens.

    The standard UV transilluminator and the white light source (a fold-down table), as well as any optional light sources, are housed dust-free inside the cabinet. The UV transilluminator can be operated at either 302 nm or 365 nm at low or high intensity. For cutting sample bands from the gel, the transilluminator slides out of the cabinet.

    Using ImageQuant TL analysis software with ImageQuant 350 provides high levels of automation, accuracy and reduces analysis time to a minimum.


    Analytical ultracentrifuge

    Analytical ultracentrifugation is used for the determination of molecules masses in solution. The instrument analyzes macromolecular sedimentation over a wide range of conditions such as concentration,temperature, ionic strength and pH.
    Sedimentation velocity and sedimentation equilibrium experiments can be done with the instrument.    The operating methodology measures the relative change in the distribution of molecular weights, providing an efficient way to measure heterogeneity, stoichiometry and self-associating systems. The XL-A/XL-I's measurements are based on the first principles of thermodynamics and hydrodynamics, no standards or calibrations are required.

    All data and images were taken from the companies sites.
