The ChemiDoc Touch Imaging System is a fully featured instrument for gel imaging and western blot imaging. Featuring a compact design that integrates an intuitive touch screen with a powerful computer, this imaging system uses application-specific trays for chemiluminescence and UV/visible fluorescence detection including stain-free gel and blot imaging (only with Bio-Rad stain-free gels).   
   
The ChemiDoc Touch System uses Image Lab™ Touch Software for image acquisition and onboard image analysis. To analyze images at your desk, install Image Lab Software on your personal computer. See the Image Lab Software page for more information and free downloads of both programs.   
   
Using the ChemiDoc Touch Imager as part of the V3 Western Workflow™ brings a new level of quality control and quantitation to the western blotting process, allowing you to visualize, verify, and validate your results at multiple points throughout the process.   
   
Applications and Uses of the ChemiDoc Touch Imaging System   
Electrophoresis — protein and nucleic acid gel documentation, stain-free protein gel imaging   
Western blotting — monitor electrophoresis, verify protein transfer, and quantitate proteins on blots   
   
Three different sample trays are available for diverse imaging applications — Smart Tray Technology™ automatically recognizes the application-specific trays and adjusts imaging parameters and software options accordingly:   
  • White sample tray for Coomassie Blue, copper, silver, and zinc stains (170-8372)   
  • Blue sample tray for nucleic acid applications with GelGreen or any SYBR® stain (170-8373)   
  • Chemi/UV/stain-free sample tray for Bio-Rad stain-free gels and blots, chemiluminescent detection, ethidium bromide, SYPRO Ruby, and more (170-8374)
