Discover the new SignaturePLUS™ imaging and analysis system from Aushon Biosystems. The system includes a CCD imager with custom optics designed specifically for quantitative chemiluminescent protein arrays, and new PROarray™ Analyst software for fast and reproducible analyses. The SignaturePLUS has the first Apple-approved iPad® touch-screen interface on a life science research instrument. Multiple exposures are used to form an expanded dynamic range curve to improve the measurement of low level samples while preventing the high level samples from reaching saturation levels.
