WesternSure Pen

“It is so nice to be able to just draw right on the membrane and then see it.”
Dr. Lisa Keyes, University of Florida

The WesternSure Pen is used to annotate visible protein ladders prior to chemiluminescent Western blot detection. The pen is optimized for detection using the C-DiGit® Blot Scanner or the Odyssey® Fc Imaging System, and is suitable for use with film or other imaging systems. This unique marker delivers an ink which emits light when incubated with commonly-used chemilumi­nescent substrates, including WesternSure PREMIUM. The ink is faintly visible for easy identification of marked membranes.
