BP Light 550 carboxylic acid

BP Light 550 carboxylic acid is a vibrant orange to red fluorescent dye that surpasses other rhodamine derivatives, such as BP Fluor 555, TRITC, and Cy3 dyes, especially in fluorescence applications. The high water solubility of BP Light Fluors allows for high dye-to-protein ratios without causing conjugate precipitation.
