Opis

Opis ogólny

CF^™488A is a green fluorescent dye optimally excitable by the 488 nm argon laser line. Under common detection conditions, CF^™488A is at least as bright as Alexa Fluor^™ 488. However, a major advantage of CF^™488A over Alexa Fluor^™ 488 is that antibody conjugates prepared from the former are biologically more specific. Alexa Fluor^™ 488 carries multiple negative charges, which can significantly change the isoelectric point of the proteins the dye labels and consequently alter the specificity of the protein conjugates. CF^™488A, on the other hand, is minimally charged. Thus, antibody conjugates prepared from the dye ensure biological detection with high signal-to-noise ratio. Another feature of CF^™488A is that the emission peak wavelength is about 10 nm shorter than that of Alexa Fluor^™ 488 and 15 nm shorter than that of the traditional green dye FITC (or FAM). The shorter wavelength of CF^™488A offers the advantage of less fluorescence "spill-over" in the red channel in multi-color detection applications.

Cechy i korzyści

1. Yields biologically more specific antibody conjugates and has less "spill-over" fluorescence in the red channel than Alexa Fluor^™488. 2. Extremely photostable. 3. Highly water-soluble and pH-insensitive.
