The ImageQuant™ LAS 500 is designed for the imaging of chemiluminescent Western blots, fluorescent proteins, DNA gel stains, and white-light imaging of colorimetric stains and markers. The system enables detection of picogram levels of chemiluminescent samples. All tasks on the ImageQuant LAS 500 are controlled via the integrated touchscreen including the automatic overlay function, which allows users to compare chemiluminescent samples to a colored molecular weight marker and estimate the detected proteins’ size and orientation on the membrane. The system is fitted with a 16-bit, 8.3 megapixel, Peltier cooled CCD camera with a 30 mm fixed-focus lens that can cool to -25°C in under five minutes.
