Gel Doc XR+ and ChemiDoc XRS+ Systems

1

Introduction Gel Doc™ XR+ and ChemiDoc™ XRS+ gel documentation systems offer high performance and ease of use. They both contain a charge coupled device (CCD) camera to capture images in real time and allow you to accurately position your sample and generate optimized image data. The Gel Doc XR+ and ChemiDoc XRS+ systems use the same lighttight enclosure (the universal hood), which contains built-in UV and white light illumination, but different CCD cameras. Both systems feature dynamic flat fielding technology for superior image uniformity and accurate quantitation. Bio-Rad Image Lab™ software controls image capture and optimization for your selected applications, analyzes results, and produces reports based on your specified output, all in a single workflow.

Gel Doc XR+ Imaging System Gel Doc XR+ imaging system is a high-resolution gel documentation system that allows fast, easy quantitation of gels and blots. Position your sample inside the imager and follow the onscreen steps to run a protocol with only one click. You can customize your applications within an existing protocol or create a new protocol using many options presented by the Image Lab software. Features include: • Detection of dynamic ranges that cover > 3 orders of magnitude • Dynamic flat fielding specific to fluorescent and colorimetric applications

Smart, application-based protocol setup using Image Lab software, which assists you by presenting appropriate filter and illumination sources for each application Ability to upgrade to the ChemiDoc XRS+ system

ChemiDoc XRS+ Imaging System In addition to the gel documentation applications of Gel Doc XR+, the ChemiDoc XRS+ imaging system offers sensitive chemiluminescent detection. The system includes a supersensitive 16-bit CCD camera that is deeply cooled for the long imaging times required for faint sample detection and for accurate quantification of image data. Features include: • Suitability for imaging applications that require excellent sensitivity (chemiluminescent western blots) • Smart, application-based protocol setup using Image Lab software, which assists you by presenting appropriate filter and illumination sources for each application • Dynamic range > 4 orders of magnitude • Flexibility to image chemiluminescent, fluorescent, and colorimetric samples with dynamic flat fielding specific to each application

System Components CCD Camera and Lenses Either the Gel Doc XR+ or the ChemiDoc XRS+ camera is placed on top of a lighttight enclosure (the universal hood) for capturing images. The camera comes with a motorized zoom lens (MZL) that allows remote adjustment of the lens control functions (zoom, focus, and iris). A patent-pending software algorithm controls the MZL, giving the user automatic image focus once an initial calibration is performed during system installation. See the Technical Specifications table, included in the chapter which discusses your camera, for complete specifications of each system. A +1 diopter lens is factory installed to allow the entire sample stage to be visible. This lens should always remain on the MZL assembly.

System Components

Universal Hood The universal hood is designed to capture fluorescent and chemiluminescent images without using a photographic darkroom. The enclosure has built-in white light epi-illumination and UV transillumination. For easy sample loading, the UV transilluminator is located in the drawer of the universal hood and can be accessed from the front of the enclosure. When not imaging, the lights in the darkroom enclosure turn off automatically. The universal hood has touchpad buttons to perform various functions; however, Image Lab software controls all of these functions remotely, removing any requirement for manual control of the lens and lights. Running a protocol overrides any touchpad input.

Image Lab Software Each system ships with a full version of Image Lab software. In addition to controlling the imager systems, image capture, and optimization, Image Lab software can be used to annotate and document images, analyze molecular weights (or base pairs, when imaging nucleic acid gels), and to determine accurate quantitation and purity of samples. You can print all or a subset of your data in a report. Alternatively, you can export your data to other software, such as Microsoft Office programs, for further analysis or presentation options. See Chapters 5 to 10 for detailed instructions on the software.

Emission Filters The universal hood can hold two different emission filters for fluorescent applications. No filter is required to image chemiluminescent samples. A standard filter (catalog #170-8081) is used for colorimetric (white light) applications and is included in the installation kit.

Gel Doc XR+ and ChemiDoc XRS+ Systems | Introduction

Optional Accessories Bio-Rad Laboratories, Inc. offers a selection of optional filters and illumination sources. See Appendix B for ordering information and a complete listing of accessory filters, UV light sources, optional parts, and replacement parts.

Printer For your convenience, Bio-Rad offers an optional USB printer for use with the Gel Doc XR+ and ChemiDoc XRS+ systems: the Mitsubishi P93DW thermal printer, (catalog #170-8089).

Conversion Screens WHITE LIGHT CONVERSION SCREEN The white light conversion screen (catalog #170-8001) is a phosphor screen that produces white light transillumination when placed on top of the UV transilluminator.

WHITE LIGHT TRANSILLUMINATOR An optional white light transilluminator (catalog #170-7950) may also be used with either system. The white light transilluminator plugs inside the universal hood and is controllable by the touchpad or the computer software.

XCITABLUE™ CONVERSION SCREEN The optional XcitaBlue screen kit (catalog #170-8182) is a UV to blue light conversion screen, which allows you to visualize DNA samples while protecting them from UV damage.

System Requirements Image Lab software runs under Windows XP Professional, Windows 7, and Mac OS X. Images scanned at high resolution can be quite large. The amount of memory required for using the program is mainly determined by the size of the images you will scan and analyze. For this reason, we recommend that you archive images on a network file server or on removable storage media. Bio-Rad can also provide an appropriate computer to use with this system. Contact your local Bio-Rad representative for more details.
