WesternBright 化学发光标记笔，可直接在预染的蛋白质marker上或者蛋白转移膜上书写，其特有的“墨水”可以和HRP底物（ECL发光液）起反应，产生化学发光信号。
优势：
更简便-- 可将蛋白质Marker转换成化学发光条带，和目的蛋白质条带一起同时成像，方便观察和分析
更人性化-- 可直接在蛋白转移膜上注明编号和日期，方便实验数据的管理
确认 HRP 底物稳定性-- ChemiPen中的试剂和HRP底物（ECL发光液）结合后可长时间发光，所以他可以用来实时检测HRP底物（ECL发光液）的稳定性
兼容性-- 可用于胶片和CCD成像

You can use the WesternBright ChemiPen to transform your visible protein markers into chemiluminescent markers, to annotate your blot with a date or blot ID, or to check the stability of your HRP substrate (Figure 1).

Figure 1. The WesternBright ChemiPen can be used to mark the location of protein standards and to annotate the blot with a date, as in the right panel.

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 (Figure 2).

The WesternBright ChemiPen 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.
