CF^TM 405S succinimidyl ester

NA.41

CF^™405S is a blue fluorescent dye with an absorption peak wavelength that nearly coincides with the 405 nm blue diode laser line. In addition, the emission peak wavelength of the dye well centers within the blue detection window of BD flow cytometers. As a result, flow cytometry analysis using CF^™405S dye results in much brighter signal than that using Alexa Fluor^® 405.

1. Much brighter than Alexa Fluor^® 405 due to better compatibility with both excitation and emission windows on commom instruments. 2. Highly water-soluble. 3. pH-insensitive.
