Bio-Rad ChemiDoc MP Gel Documentation System

The ChemiDoc System is based on CCD high-resolution, high-sensitivity detection technology and modular options to accommodate a wide range of samples and support multiple detection methods including fluorescence, colorimetry, densitometry, chemiluminescence, and chemifluorescence. The system is controlled by Image Lab software to optimize imager performance for fast, integrated, and automated image capture and analysis of various samples.

The system accommodates a wide array of samples, from large handcast polyacrylamide gels to small ReadyAgarose Gels and various blots. The system is an ideal accompaniment to PCR, purification, and electrophoresis systems, enabling image analysis and documentation of restriction digests, amplified nucleic acids, genetic fingerprinting, RFLPs, and protein purification and characterization.

The ChemiDoc System offers fast and sensitive chemiluminescence detection in addition to gel and blot documentation of fluorescent and colorimetric samples. The system includes a supersensitive 16-bit CCD camera that is supercooled for detection of faint samples. The ChemiDoc XRS+ system can be used for imaging with a wide variety of applications that require high resolution and sensitivity (such as chemiluminescent western blots).

The ChemiDoc System eliminates the need to use costly and unreliable X-ray film technologies while providing quantitative and reproducable data in seconds. The system features a signal accumulation mode (SAM), which guides a user through determining optimum exposure time and capturing a desired image of a chemiluminescent sample.
