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 orange fluorescent dye CF™543. CF™543 is an orange fluorescent dye with an excitation spectrum optimally matching the 543 laser line. Antibody conjugates of the dye are much brighter than those of Alexa Fluor® 546. To minimize cross-reactivity, the antibody has been adsorbed against human, mouse and rat serum.
