The ChemiDoc MP imaging system enables stain-free operation and lets you visualize proteins at every stage of your experiment. Its flexibility and sensitivity are complemented by a simple, intuitive operation that integrates seamlessly into your workflow.

Features and Benefits

  • Stain-free technology — eliminates extra steps and allows you to check electrophoresis results and transfer performance before western blotting, conserving precious samples and reducing waste
  • Ease of use — auto-focus, auto-exposure, and simple operation mean that with little or no training, you can acquire publication-quality images in seconds
  • Versatility — can be used for a variety of sample types or experiments that require differing detection methods, including chemiluminescence, multiplex fluorescence, and routine gel imaging as well as for colorimetric gel and blot documentation
  • Image quality — exceptional resolution and dynamic range eliminate cross talk and deliver publication-ready images in seconds
  • Sensitivity — advanced detection technology creates optimal exposure even for faint and intense band
