Bio-Rad Universal Hood II Gel Documentation System

Bio-Rad Universal Hood II Gel Documentation System

Cambridge ID #: 20100

Includes:

  • Cabinet & Camera
  • Computer With Software
  • Manual

 

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.

 

Specifications:

  • CCD Resolution (HxV): 1,392 x 1,040µm

Stratagene UV Stratalinker 2400 UV Crosslinker

Stratagene UV Stratalinker 2400 UV Crosslinker

Cambridge ID #: 20447

Descriptions:

The Stratalinker UV crosslinker is designed to crosslink DNA or RNA to nylon, nitrocellulose, or nylon-reinforced nitrocellulose membranes.

For optimal cross linking performance, each Stratalinker UV crosslinker is equipped with an internal photodetector designed to compensate for the natural shift in power output of aging ultraviolet bulbs.

 

Features:

  • 254-nm UV light bulbs, 15 Watts each
  • For Crosslinking DNA or RNA to Coated Glass Slides, Nylon, Nitrocellulose or Nylon-Reinforced Nitrocellulose Membranes
  • Greatly Reduces Valuable Time From Several Oven Baking Hours to 30-60 Seconds
  • Increases Hybridization Signal Compared to Oven Baking

Beckman Coulter Vi-Cell Auto Cell Viability Analyzer

Beckman Coulter Vi-Cell Auto Cell Viability Analyzer

Cambridge Scientific ID #'s: 14345, 14264, 14344

The new Vi-CELL Series Cell Viability Analyzers provide an automatic and cost effective means to perform the trypan blue dye exclusion method. This data is essential to the decision making process for basic tissue culture cell passage and maintaining optimum culture conditions in bioreactors. Cell and tissue culture applications in life science research, including recombinant protein and biopharmaceutical production, require the accuracy, precision and automation available only in the Vi-CELL cell viability analyzer.
