Polyclonal anti-RFP is designed to detect red fluorescent protein (RFP) and its variants. This product is prepared by labeling high quality polyclonal rabbit anti-RFP IgG (H+L) with the red fluorescent dye CF™568. CF™568 is a red fluorescent dye with an excitation spectrum optimally matching the 568 nm line of the Ar-Kr mixed-gas laser. Antibody conjugates of the dye are much brighter than those of Alexa Fluor® 568. In addition, the photostability of CF™568 is superior to that of Alexa Fluor® 568, making CF™568 a much better choice for demanding applications, such as confocal microscopy and single molecule imaging. To minimize cross-reactivity, the antibody has been adsorbed against human, mouse and rat serum.
