AF 594 is a bright water-soluble dye that is not sensitive to pH changes within the range from 4 to 10. This red-fluorescent dye is commonly used for flow cytometry and fluorescent microscopy.
AF 594 NHS ester is used for labeling proteins, peptides, antibodies, and any molecules containing an -NH2 group (such as amino-modified oligonucleotides); it results in the formation of stable amide bonds between the dye and the target molecule. The best result in conjugation reaction achieved at pH from 7 to 9.
AF 594 can be used for protein labeling with a high molar dye-to-protein ratio. The resulting conjugates with a high degree of labeling (DOL) do not exhibit significant fluorescence quenching. In contrast, the conjugates have brighter fluorescence, which allows increasing the lowest limit of detection of the labeled product.
