Section 1 Introduction
The Bio-Rad Gel Doc ™ XR and ChemiDoc
™
XRS gel documentation systems are easy-to-use, high-
performance systems. They use a charge coupled device (CCD) camera to capture images in real time,
which allows you to more accurately position and focus the image. With Bio-Rad Quantity One
®
software,
acquired images can be optimized, annotated, analyzed and printed.
The Bio-Rad Gel Doc XR and ChemiDoc XRS systems utilize an enclosure (Universal Hood II) that is
light-tight and contains UV illumination and white light illumination. Please note that both the Gel Doc XR
and ChemiDoc XRS cameras have external power supplies.
1.1 Computer Requirements
This software will run under Windows XP, Vista Ultimate, or Mac OS X. The amount of computer memory
required for using the program is mainly determined by the size of the images you will scan and analyze.
Images scanned at high resolution can be quite large. For this reason, we recommend that you archive
images on a network file server or removable storage media.
