应用
AMCA是一种用于标记蛋白的试剂。其在345 nm处具有特征吸收峰以及在440-460 nm处具有荧光发射（蓝色区域）；然而，当与蛋白质缀合时，吸收峰移至355 nm，并在440-460 nm处发射荧光。其具有高的荧光产量和足够的斯托克斯位移（100 nm），并且相对光稳定 。其相对容易被激活并偶联至肽的N端氨基，从而形成酸稳定的酰胺键 。
包装

Antibodies coupled to 7-aminocoumarin (AMCA) emit a bright blue fluorescence under ultraviolet (UV) excitation and are therefore ideal for three-color immunofluorescence (IF) with fluorescein (FITC) and phycoerythrin (PE) labeled reagents; however, due to the different absorption spectra, the use of
