Transform your protein standard into a chemiluminescent marker !

Write or draw on your transfer membranes with the WesternBright ChemiPen.
With the proprietary "ink" you can make pre-stained protein standards chemiluminescent, annotate your blot with a date or blot number, or check the quality of your HRP substrates.

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.
