BDP FL NHS ester

分子式:C18H18BF2N3O4

分子量:389.16

CAS 号:146616-66-2

外  观:橙色固体

产品特性:

BDP FL NHS酯是用于488 nm通道的高级染料,是荧光素的替代品,荧光素与BODIPYFL®相同NHS酯。一种用于标记蛋白质和肽的氨基反应性染料。

 

虽然此分子的吸收光谱和发射光谱保留在FAM激发和发射通道内,但这种染料提供更好的光稳定性和出色的亮度。BODIPY-FL的荧光光谱窄于FAM。当发射波长可以达到最大值时,这为基于单色仪的仪器提供了更好的亮度调整到最大染料。

 

该染料是中性的,具有低分子量,并在结合物中保留了高量子产率。

 

该染料是荧光素(FAM),BODIPY-FL,Alexa Fluor 488,DyLight 488,Cy2和其他488 nm染料的良好替代品。
