GE Healthcare Life Sciences Data file 28-9610-75 AC Imaging systems, software, and accessories ImageQuant™ LAS 4000 mini biomolecular imager ImageQuant LAS 4000 mini (Fig 1) is a compact solution designed for sensitive digital imaging of Western, Northern, and Southern blots for the purposes of quantitation and documentation. ImageQuant LAS 4000 mini delivers: • Wide linear dynamic range: Capture and precisely quantitate weak and strong signals over four orders of magnitude in the same image, avoiding time-consuming multiple film exposures. • High resolution: Accurate quantitation of gels and films up to 18 × 12 cm in size. Up to 6.3 Mpixel resolution is achieved via a unique diagonal pixel configuration. • Low noise: The camera is typically cooled to -25°C (maximum -35°C) enabling longer exposure times giving less background, which is especially important for precise quantitation of very weak signals in chemiluminescent Western blotting. • High sensitivity: ImageQuant LAS 4000 mini captures fluorescent and chemiluminescent signals on a Western blot down to picogram levels of target protein. Sensitivity may be increased by binning of up to 8 × 16 pixels. • Uniform quantitation: Distortion, dark frame, and flat frame corrections are applied to each imaging mode for optimal precision. Description ImageQuant LAS 4000 mini is a biomolecular imager for the detection and quantitation of chemiluminescence. Fig 1. ImageQuant LAS 4000 mini biomolecular imager for chemiluminescence is quantitative, with high sensitivity and resolution. The system consists of an intelligent dark box, camera, lens, and an epi-white light source for focusing purposes. Automated iris and focus allows image optimization without having to open the cabinet. Focusing and exposure time are remotely controlled from a computer. High resolution and precise quantitation of low signals are achieved using a multipurpose 16-bit, 3.2 Mpixel camera fitted with a large aperture F0.85 lens. The system responds rapidly when changing settings and focus. The system can be upgraded in your lab with a UV transilluminator for imaging DNA visualized with ethidium bromide (EtBr) or protein stained with, for example, Deep Purple™ Total Protein Stain, and with blue epifluorescence for imaging SYBR™ Green and SYPRO™ Ruby.

Technical features Table 1. ImageQuant LAS 4000 mini specifications Sensitive chemiluminescence detection: The system is designed for imaging chemiluminescent Western blotting reagents. The system can be upgraded with a UV transilluminator to handle UV fluorescence imaging of gels stained with EtBr or Deep Purple Total Protein Stain, and upgraded with a blue epi-fluorescence module for imaging SYBR Green, FITC, FAM™, and EGFP. The UV transilluminator can also be used for imaging colorimetricstained samples (e.g., Coomassie™ Blue and silver stain) with the addition of the Pink Calibration...
