Molecular Imager GS-800™ USB Calibrated Densitometer (170-7983)

"The gel scanner is really easy to use, and an ideal size to put on to the bench. The software to control the scanner is very straightforward and easy to use, which is great for any lab member. The scanner boots up and scans quickly producing good quality images. There are many settings in the software that enable you to get the best image possible. This is an ideal and extremely useful piece of equipment, particularly for labs that routinely work with gels and western blots."

Description

 

The GS-800™ Calibrated Densitometer offers superior accuracy, sensitivity, and data reproducibility. It automatically self-calibrates the optical density to optimize detection.

Features Include:

  • Transmissive and reflective imaging using red, green, and blue CCD technology to scan chromogenic samples at the optimal detection wavelength
  • Imaging of a wide variety of samples such as 1-D and 2-D gels, colorimetric dot and slot blots, film-based chemiluminescent blots, autoradiograms, slides, and photographs
  • IQ/OQ for verification of the reflectance and transmittance calibration functions
  • High resolution and analysis of closest bands on a gel due to 12-bit precision and 36.3 μm resolution
  • Scanning of larger gels for enhanced separation of proteins on oversized 29 x 40 cm sample platen
  • Accurate quantitation of samples, such as Coomassie Blue– and silver-stained gels, over a large dynamic range (0–3.0 OD)
  • Sealed imaging platen to accommodate wet samples of variable thickness
  • Purity analysis and lane background tools for manufacturing QC

Transmittance and Reflectance Unlike laser densitometer systems, the GS-800 calibrated densitometer has both transmittance and true reflectance capabilities that allow accurate scans of both transparent and opaque samples.

The advantage of true reflectance scanning is accurate detection and analysis of molecules on the surface of membranes, rather than molecules distributed throughout the membrane matrix. True reflectance provides the most accurate detection and analysis of dot blots, slot blots, and other electrophoretic blots without quantitation error.

IQ/OQ The calibration of the GS-800 calibrated densitometer can be validated by following GS-800 IQ/OQ protocols.These protocols are available as an accessory to the GS-800 densitometer. The easy-to-follow protocols include instructions for installation of the hardware and software and for verification of the calibration functions.
