CF^TM660C maleimide

半岛bd体育手机客户端 说明

一般描述

CF^?660C and CF^?660R are two spectrally similar fluorescent dyes that emit fluorescence at about 685 nm in the borderline spectral region between far-red and near-IR. Although their absorption maxima are at around 660 nm, both dyes can be sufficiently excited by the 633 or 635 nm laser. When combined with other CF^?dyes of shorter wavelengths, CF^?660C or CF^?660R can serve as a useful long wavelength dye in multi-color detection applications. The two dyes are spectrally similar to Alexa Fluor^?660 but are far superior to the latter in performance. Like Alexa Fluor^?660, CF^?660C is a cyanine-based dye. However, when conjugated to protein, CF^?660C is several fold brighter and significantly more photostable than Alexa Fluor^?660.

特点和优势

1. Much brighter than Alexa Fluor^?660. 2. More photostable than Alexa Fluor^?660. 3. Highly water-soluble.
