(DB-410112)
AF 488 TCO is a bright green-fluorescent dye that is structurally identical to Alexa Fluor 488. With its high photostability and pH resistance, it has become one of the most widely used fluorophores in life sciences. Its hydrophilic nature makes it an ideal choice for labeling sensitive proteins.
AF 488 with trans-cyclooctene (TCO) readily reacts with tetrazines and possesses ultrafast kinetics, selectivity, and long-term aqueous stability, which is important in low-concentration applications such as protein-protein conjugations.
