BDP 558/568 is a fluorophore with a fluorescence maximum at 569 nm (in the yellow spectrum range). This dye has a low Stokes shift, high quantum yield; it is hydrophobic and relatively non-sensitive to pH changes or solvent polarity. By its spectral characteristics, BDP 558/568 is an analog of such fluorophores as BODIPY™ 558/568 and Cy3™. BDP 558/568 maleimide can be used for conjugation with peptides, proteins, antibodies, or other molecules that contain free thiol groups (-SH).
BDP 558/568 是一种荧光团，最大荧光波长为 569 nm（在黄色光谱范围内）。 该染料具有低斯托克斯位移、高量子产率； 它是疏水的，对 pH 变化或溶剂极性相对不敏感。 根据其光谱特性，BDP 558/568 类似于 BODIPY™ 558/568 和 Cy3™ 等荧光团。 BDP 558/568 马来酰亚胺可用于与肽、蛋白质、抗体或其他含有游离硫醇基 (-SH) 的分子结合。
