CoraLite Plus spectra

CoraLite Plus dyes 的亮度與 Alexa Fluor® dyes 相當。由於重疊熒光光譜最小，可同時用於共定位研究（co-localization studies）

FlexAble 的 CoraLite Plus 系列實現更快、更簡單的多重檢測。未來還會新增更多 dyes/specificities ~ This is just the start!

應用項目 Immunofluorescence (IF), Western blotting (WB), Flow cytometry (FC)

Antibody labeling with FlexAble 原理

FlexLinker 以高親和力、非共價的方式進行抗體標記 (Fc region of antibody)，一旦結合就不會從抗體中釋放出來，而未與抗體結和的 FlexLinker 將被 FlexQuencher 中和 ( Neutralization )。

Proteintech 一鍵優化實驗流程 ( 標記一抗 0.5 µg )

It's easy as 1, 2, 3
3步驟, 10 分鐘, 完成標記

Step-by-step workflow of Proteintech's FlexAble antibody labeling kit shows 30 seconds hands-on time and ready-to-use in less than 10 minutes

* 根據一抗標記量，適當比例調整試劑體積

Multiplexing (可應用於多重染色 排除物種交叉反應 )

同物種的一級抗體，須分別標記。標記完成，可將其合併應用

FlexAble provides the easiest way to multiplex antibodies from the same species and isotype

不同物種的一級抗體可以在同一試管中混合，使用相對應物種的 FlexLinker 同時進行標記

Primary antibodies of different species can be labeled simultaneously in the same tube with FlexAble antibody labeling kits.
