The ChemiDoc Touch Imaging System is a fully featured instrument for gel imaging and western blot imaging. Featuring a...
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:
