Bio-Rad Versa Doc 4000

The VersaDoc™ Model 4000 is a versatile imaging system with numerous applications.  One of those applications is imaging planar based arrays.  These arrays, known as Quansys Multiplex ELISAs, are protein arrays preassembled in the bottom of a 96 well plate.  Using the VersaDoc Model 4000, the chemiluminescent response produced by the multiplex ELISA is visualized and recorded as a TIFF image file.  Image analysis, curve fitting and sample calculations are facilitated by importing the VersaDoc Model 4000 generated image into Quansys Q-View Software.   In order to help educate the customer on how to use the VersaDoc Model 4000 for the Q-Plex technology, a training video has been made.

The VersaDoc™ Model 4000 imaging system is used to capture digital images from single- and multicolor fluorescence, chemiluminescence, chemifluorescence, and colorimetric samples. The system uses a back-illuminated, high-sensitivity with microlens technology CCD detector and flat fielding technology and includes a 50 mm and 20-40 mm zoom lens, sample tray, cleaning kit, Quantity One software for PC, and instructions. Dimensions are 58 x 66 x 99 cm.

The Model 4000 is the ideal proteomics imager, offering great flexibility (image chemiluminescent western blots, SYPRO Ruby-stained 2-D gels and Coomassie Blue-stained 1-D gels) and state-of-the-art CCD resolution (3.2-megapixel). The megapixel camera provides a maximum resolution of approximately 50 m.

Some of the camera specs are front-illuminated, high-sensitivity CCD with microlens technology, full-Frame CCD utilizes its entire surface to collect light, 3.2-megapixel (2,184 x 1,472 pixel array), 12-bit, >3 orders of magnitude dynamic range, Peltier cooled.

For assistance on using this device with the Q-Plex arrays, contact us for more information on how to set up this imager and to optimize your results by increasing the dynamic range of your assay as well as removing vignetting and parallax using the Q-View software.
