TRITC-dextran, MW 40000

TRITC-dextran MW 40000 (Tetramethyl rhodamine isothiocyanate glucan, MW 40000) is a fluorescent dye with a molecular weight of 40 kD. It has an excitation wavelength of 555 nm and can penetrate blood vessels, making it suitable for labeling plasma to visualize the vascular system. TRITC-dextran MW 40000 is used in drug delivery due to its stability across a wide pH range (pH 2–11) and resistance to photobleaching.
