Eli.Punch ist a tool to easily transfer the well membranes of 96 well Millipore plates to the adhesive foil Eli.Foil. These foils can be read in by our Eli.Scan or Eli.Scan+ instruments. In addition it’s a suitable solution for a space saving storage of your ELISPOT assays


Eli.Foil is a specially designed adhesive foil for punching out the membrane bottoms of 96 well Millipore plates. The foil contains glue only at the locations where the well bottoms will be sticked. This means no more sticking between the bottoms, on the scanner, at your fingers or in your lab journal

Cirascan™ is a specially designed imager that captures multiple images from a Ciraplex array, using an astronomy-grade cooled CCD camera with high-end optics. The imager uses a patent pending multiple exposure image acquisition algorithm to produce a high resolution composite image of each chemiluminescent array plate. An easy to use interface allows new users to operate Cirascan with minimal training. Simply prep samples using familiar ELISA protocols, place the plate into the compact, benchtop imager, and receive fully analyzed results within minutes!

Cirascan’s intuitive Apple iPad touch screen user interface allows researchers to select a plate layout created at their desktop computer and enter it on Cirascan via a network connection, Sample identification information can be entered directly into a plate layout with the optional Cira™ barcode reader

Cirascan™ is designed to capture a series of images, offering an improved broader dynamic range of assay quantification. Rapid imaging (typically <2 minutes per plate) and a fixed-focus setting – so no focus adjustments are required from one image to the next – make it easily shared by multiple users. Plus, automated calculations of image time make the instrument incredibly easy to use.

  • Complete System: Imager (integrated with embedded Mac mini computer and iPad™ user interface), and array analysis software
  • Performance: Improved sensitivity and dynamic range
  • Fast: Typically generates 16-bit images in <2 minutes
  • User-friendly: Integrated touch screen user interface for image capture and storage; Fixed-focus setting and automatic calculation of optimal image times
  • Accuracy: Customized array software locates each spot in the image, measures density values and calculates pg/ml values for unknown samples from standard curves. Spot location and analysis is automatic and rapid. Providing nearly immediate access to measured sample concentrations.
  • Quality: Custom, high resolution camera/lens for improved image quality and more consistent results
  • roductivity: Image acquisition can take place at the bench, analysis at desk – freeing the imager for other users or to run more plates.
  • Secure: Images can be archived for a permanent record of raw experimental data
  • Set-up: Simple, fast, out-of-the-box installation – ready to use with minimal instruction
  • Compact: Uses <2 sq.ft. of bench space; All components integrated with embedded MacMini and iPad user interface, eliminating need for separate system components

CometAssay® Electrophoresis System



  • Maintains constant buffer temperature with cooling pack chamber and one-piece molded plastic body.
  • Maintains optimal buffer level for consistent results with overlay.
  • Specially designed trays accommodate 2, 20 and 96 well slides and maintain correct position during electrophoresis.
  • Optimized for use with CometAssay Kits and CometAssay Control Cells.
  • Available with area specific power supply.

Trevigen's CometAssay® ES Il enables investigators to consistently optimize alkaline and neutral comet assays for highly reproducible results, and to standardize electrophoresis methods between individual users and laboratories. Comet assay results can be variable depending on temperature, distance between electrodes, and buffer height. Trevigen has solved these problems by developing a specialized electrophoresis unit.


Trevigen’s 96-Well CometChip® System (Figure 1) is a high through-put 96 well platform to treat, electrophorese and measure DNA damage, in one or more cell types, on a single slide using the comet assay. The CometChip® is an array of spatially encoded micropores patterned on agarose. 96 separate macrowells, each containing ~400 micropores, are created by inserting the CometChip® into a magnetically sealable cassette. Cells added to each macrowell are deposited by gravity into the micropores - creating a pattern of non-overlapping cells (Figure 3A, Section IX Data Interpretation).

Multiple experimental conditions are performed and evaluated in parallel by the addition of different chemicals to respective wells. Once treatment is complete and the CometChip® removed from the magnetic cassette, an LMAgarose overlay is added to immobilize the cells within the micropores. When performing the Alkaline CometAssay®, the CometChip® is immersed in Lysis Buffer for gentle cellular lysis, followed by Alkaline Solution to unwind and denature the DNA and hydrolyze sites of damage. Comets are developed by alkaline electrophoresis using Trevigen’s CometAssay® Electrophoresis System. Subsequent staining with SYBR® Gold, a fluorescent DNA intercalating dye, allows visualization of the comet tail shape for assessment of DNA damage by fluorescence microscopy.
