Description
The PowerScanner is Tecan’s open-format microarray scanner, designed for imaging of regular and high density microarrays of tissues, proteins and nucleic acids.
• High resolution – from 2 to 40 μm, with two configurations available (4 μm system is upgradable to 2 μm)
• Excellent sensitivity – offering outstanding signal-to-noise ratio for reproducible detection
• Large dynamic range – plus multiple scans at varying gain
• Unrivaled versatility – allowing the widest possible range of applications
Manufacture Specifications:
Dynamic range
• Real 16 bit TIFF images
• Signal-to-Noise ratio at 2 μm pixel size on 20 x 20 μm feature area > 2 x 105
• Average spatial crosstalk between spots – < 3 % on high density arrays – < 0.1 % on regular density arrays
• Increase dynamic by normalizing on two gain levels
Scan area dimension
• Max 75 x 22 mm size
• Easy and intuitive graphical definition of scan areas can be done directly in pre-scan images or in default slide graphic of the GUI
• Multiple scan areas for multi-pack-array slides can be defined for breaking down individual assays into small individual images for storage and analysis
Resolution (Pixel Size)
• A-type system*: 2, 4, 5, 10, 20, 40 μm
• B-type system*: 4, 5, 10, 20, 40 μ
