TRITC-dextran, MW 40000 (Tetramethyl rhodamine isothiocyanate glucan, MW 40000) is a fluorescent dye, with the molecular weight of 40 kD. TRITC-dextran MW 40000 exhibits an excitation wavelength of 555 nm. TRITC-dextran MW 40000 is vessel penetrate, which could label blood plasma to visualize the vasculature. TRITC-dextran MW 40000 is utilized in drug delivery for the stability of TRITC over a wide pH range and resistance to photo-bleaching[1][2][3].
