WesternBright 化學發光標記筆，可直接在預染的蛋白質marker上或者蛋白轉移膜上書寫，其*的“墨水”可以和HRP底物（ECL發光液）起反應，產生化學發光信號。
優勢：
更簡便-- 可將蛋白質Marker轉換成化學發光條帶，和目的蛋白質條帶一起同時成像，方便觀察和分析
更人性化-- 可直接在蛋白轉移膜上注明編號和日期，方便實驗數據的管理
確認 HRP 底物穩定性-- ChemiPen中的試劑和HRP底物（ECL發光液）結合后可長時間發光，所以他可以用來實時檢測HRP底物（ECL發光液）的穩定性
兼容性-- 可用于膠片和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.
