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 features best-in-class sensitivity and image quality plus a linear dynamic range and signal-to-noise ratio superior to film imaging. The touch-screen user interface running Image Lab™ Touch Software is easy to learn and use and optimizes performance for fast, integrated, and automated image capture of various samples.

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.

Features and Benefits of the ChemiDoc Touch Imaging System

  • High-performance imaging — get the sensitivity of film without the hassles of film processing and its inherent pitfalls; combining this sensitivity with a suite of software tools to optimize imaging and quantitation provides an unmatched ability to resolve both the faintest and most intense bands into meaningful data
  • Easy, flexible interaction — Image Lab Touch Software takes the guesswork out of imaging and puts publication-quality images at your fingertips in seconds. Acquire images with a rapid 3-step protocol, then engage a full complement of digital tools to assess, select, and export your images
  • Stain-free imaging capability — the ChemiDoc Touch Imaging System supports Bio-Rad’s unique stain-free gel technology, enabling you to image gels in 5 min without staining, and quantitate bands by total protein normalization

Learn how you can streamline your western blotting protocol and validate your results at each step with the V3 Western Workflow.

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)
