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. The reagent in the ChemiPen adsorbs to nitrocellulose and PVDF membranes, and reacts with HRP substrates to produce chemiluminescence that can be detected with X-ray film or CCD imaging.
• Improve accuracy - transform your visible protein ladder standard into a chemiluminescent standard on your Western blot.
• Annotate - permanently mark your blots with the date or blot ID.
• Confirm HRP substrate stability - the ChemiPen reagent glows when incubated with an HRP substrate, so it can be used to test substrate stability.
• Compatible - with both X-ray film and CCD imagers.
