Technology that enables you to do more, see more, and discover more
After a single scan, your C-DiGit image file is a complete picture of all the data for each Western blot. Unlike film, there’s no need for multiple exposures to view strong bands and faint bands, or to make sure you’ve captured all the information you might need in the future. ECL requires you to move fast to capture signals before they’re gone. Skip the darkroom with direct digital capture, and get your results immediately – ready for analysis and publication.

C-DiGit signals are proportional to light response, contributing to a wide linear dynamic range. Conversely, the response of film to light is governed by the reciprocity law: film response is supposed to be proportional to light intensity and duration of exposure.
When light intensity is very low, film response is lower than expected due to the photochemistry of creating a latent image. This causes faint signals to drop off abruptly on film, where a gradual decrease is expected. At the other end of film response, very strong signals exhibit high-intensity reciprocity failure. When this happens, film response plateaus and can no longer accurately record signals.

The advanced optical design of the C-DiGit combines the advantages of film and CCD imaging. Like film, the C-DiGit has a short working distance for efficient signal capture, and it also has an immediate digital output (similar to CCD imagers). Choose the scan sensitivity you need: “standard” for strong signals (6 minute scan), or “high” for blots with less intense signals (12 minute scan).
Short scan times produce less dark noise – without requiring expensive sensors or supercooling. These short scan times are possible with fast line-reads that quickly capture data across the entire blot.
