Boston-based PerkinElmer Life and Analytical Sciences http://las.perkinelmer.com has introduced the ProXPRESS™ 2D Proteomic Imaging System. A second-generation instrument, the ProXPRESS 2D is "improved with regard to speed, sensitivity, and flexibility," says Alessandra Rasmussen, business unit leader for proteomics and array systems.

At the heart of the new imaging system is a CCD camera that offers higher throughput with significantly increased sensitivity and resolution. The camera can scan a dozen large-format (up to 27 cm × 33 cm) gels per hour, more than double the rate possible with the previous model. Offering a slightly wider dynamic range than its forerunner (the ProXPRESS), the ProXPRESS 2D can detect virtually any probe with emission spectra falling in the long-wavelength UV or visible ranges, including SPYRO and cyanine dyes, silver stain, and Coomassie™ Brilliant Blue.

The system supports fluorescence, luminescence, absorbance, and reflection detection. It cannot be ...
