GE Typhoon 9410 imager

A microarray slide, spotted with cDNA from Microarray ScoreCard control plate and cDNA from Incyte Genomics, Inc. was hybridized with 25pmol of Cy3 labeled skeletal muscle mRNA and Cy5 labeled liver mRNA. The slide was scanned on Typhoon9410 at 10µm pixel size resolution. (from GE Healthcare)

  • Versatile system handles gel sandwiches, agarose and polyacrylamide gels, membranes, microplates, and even microarrays.
  • Powerful excitation sources and innovative high-quality confocal optics allow for the sensitive detection of low-abundance targets.
  • Red-, green-, and blue-excitation wavelengths and a wide choice of emission filters enable imaging of an extensive variety of fluorophores.
  • Automated four-color fluorescence scanning allows multiplexing of multiple targets in the same sample ensuring accuracy of analysis, increasing throughput, and saving time.
  • Storage phosphor technology delivers high-resolution imaging and accurate quantitation of 3H, 14C, 125I, 32P, 33P, 35S, and other sources of ionizing radiation.
  • Highly sensitive optics enable direct chemiluminescent imaging without intermediate exposure to films or screens.

Typhoon 9410 Variable Mode Imager unites proven storage phosphor autoradiography technology with four-color, nonradioactive fluorescent labeling techniques. For DNA, RNA, and protein samples, choose from:

  • Storage phosphor autoradiography
  • Direct blue-excited fluorescence (457, 488 nm)
  • Direct green-excited fluorescence (532 nm)
  • Direct red-excited fluorescence (633 nm)
  • Chemiluminescence

When one of the scanning modes is selected, the appropriate optical components are automatically activated. Typhoon scans gels, blots, and mounted or unmounted storage phosphor screens up to 35 × 43 cm. The instrument exhibits outstanding linearity, quantitative accuracy, and extremely low limits of detection.
