Description:

The Bio-Rad Model 3000xi Computer Controlled Power Supply produces a constant voltage to 3,000 volts, constant current to 300 mA, and constant power to 400 watts. This fully switching, microprocessor controlled unit may be used with any electrophoresis instrument. The high outputs make the Model 3000xi Power Supply ideal for electrofocusing, DNA sequencing, and isotachophoresis. The supply is useful as a general purpose instrument, and is recommended for SDS-PAGE electrophoresis, two-dimensional electrophoresis, native gel electrophoresis, electrophoretic blotting, and DNA/RNA separations. The 3000xi Power Supply is a fully programmable and computerized instrument that incorporates several unique features. The supply offers four operating modes: standard, time, volt-hour, and step. The operator has a choice of running electrophoresis manually, for a set period of time, or for a set number of volt-hours. These parameters can be combined using the step mode. While operating in any one of the four modes, the user simply enters the desired power conditions and begins the run. The operation parameters are displayed on the LCD. Output voltage, current, and power are displayed on the LED display. Electrophoresis running conditions can also be programmed. Up to 10 routines can be saved in the Model 300xi Power Supply's memory, where they can be recalled at any time. This is especially useful when using the special step mode which allows three separate electrophoresis running conditions to be programmed simultaneously. A single gel can then be run safely at three different power conditions without the need for constant monitoring.

The Bio-Rad ChemiDoc XRS System is Bio-Rad’s most advanced imaging system. The system is able to image chemiluminescent, fluorescent and colorimetric samples and comes complete with a compact darkroom, transilluminator and supercooled high resolution 1.44 megapixel CCD camera. The entire system is controlled by the provided Quantity One 1-D analysis software with additional controls on the compact darkroom to control focus, aperture and zoom. Consequently, the ChemiDoc XRS system is extremely flexible and can be used for imaging a diverse range of applications such as Western blotting, DNA/RNA gel electrophoresis, 2-D gel electrophoresis, densitometry, etc. The system is able to detect HRP and AP chemiluminescence, ethidium bromide, SYBR Green, green fluorescent protein, silver stain and Coomasie brilliant blue staining to name but a few that are frequently used with the above applications. The system features flat fielding technology which allows for superior uniformity and quantification. Flat-fielding is a technique that corrects for pixel-to-pixel variations by dividing the gain variations out of an image, thus flattening the relative response for each pixel.

Operation of the system is very simple. The gel or membrane is placed on the transilluminator, which is set into a drawer which can be moved in and out of the darkroom, facilitating placement of the gel or membrane. Once the gel or membrane is placed, it and the transilluminator are returned to the darkroom and the door closed. With the Epi-illumination switched on, the aperture, zoom and focus are adjusted using the touchpad on the darkroom and viewed on the computer monitor until the desired position, size and focus of the gel are achieved. To acquire the image, the appropriate light source for the gel or membrane is selected and the software is used to select an integration time. Using the Quantity One software, the image is frozen when a satisfactory image is acquired. The Quantity One 1-D image analysis software aids the user in obtaining the best images possible from the gel or membrane. The software is user-friendly and equipped with built-in quick guides and wizards to facilitate the optimization of images and printouts. The software is compatible with both Microsoft Windows and Macintosh platforms. The Quantity One 1-D software is used for analysis of 1-D electrophoresis gels, Western blotting membranes, Coomassie-stained SDS-PAGE gels, etc. whereas the PDQuest 2-D analysis software is also available and is intended to be used for comparative analysis where many 2-D gels are analyzed at once.
