Write or draw on transfer membranes with the ProSignal® ECL Marker. The reagent in the ECL Marker adsorbs to nitrocellulose/PVDF membranes, and reacts with HRP substrates to produce chemiluminescence that can be detected with X-ray film or CCD imaging. With the proprietary """"ink"""" any visible protein markers can be transformed into chemiluminescent markers. The ProSignal® ECL Marker can also be used for annotating blots with a date or blot ID, or for checking the stability of your HRP substrate.

The ProSignal® ECL Marker has two tips, a fine tip at one end that is perfect for writing on the blot or tracing the bands of a visible protein standard, and a thicker wedge tip that can be used to deposit greater amounts of reagent on the blot. Marking the location of visible protein standards on a blot is easy: simply trace the visible markers on the membrane after transfer and before blocking.
