Photo of a scanner digitizing Western blot results.

Although there is technology available that can take a direct digital image of a Western blot, we don’t have it in my lab. What we do have is x-ray film. It may be old school, but it gets the job done. We expose the Western blot to the x-ray film for various amounts of time, hoping to get the right exposure for that publication-quality image.  The film is then scanned to create a digitized computer image.

In this photo, there are several little Western blot results on a single piece of x-ray film.

For more information on how a Western blot is done, see this blog post.
