Antonia Red™ is a novel red-shifted dye developed at TdB Labs(1). The dye residue exhibits high photo-and chemical stability and bright fluorescence. xcitation maximum at 583 nm and an emission maximum at 602 nm.
Non-pH dependent.
Derivatives: Antonia Red™-dextran and Antonia Red-lysine-dextran.
Applications: mainly used for studying of permeability and microcirculation. Lysine-dextran derivative with Antonia Red enables fixation of cells and tissue.
Antonia Red dextrans exist in different MW (4-150 kDa) and give particle-free formulations with excellent water solubility.
