An orange fluorescent, amine-reactive dye for preparing antibody, protein and oligonucleotide conjugates.
Thermo Fisher Scientific Alexa Fluor™ 555 NHS Ester (A20009) attaches an orange fluorescent label to primary amines on proteins, peptides, amine-modified oligonucleotides and other suitable molecules.
The dye combines water solubility with fluorescence that remains insensitive to pH changes between pH 4 and 10. With conjugate excitation and emission maxima of approximately 555 and 572 nm, it supports imaging and flow cytometry in orange fluorescence channels. Invitrogen™
