荧光红Mega 490

荧光红Mega 490和其他Mega染料是专为多色技术设计的；其特征是最大激发和发射最大值之间的斯托克位移。这种染料特别适合于用氩激光或其他短波长激发光激发。这也意味着，可以用与荧光素和其他广泛使用的染料以及其他Mega染料相同的光源或滤光片布置来激发它。由于发射波长不同，可以在同一实验中独立检测出几种不同的标记。由于Mega标签的尺寸较小，并且无需使用FRET机制即可将激发光直接转换为发射光，因此我们可以预见到各种可能的应用，包括DNA测序和FISH显微镜检查。

Fluorescent red Mega 490 and other Mega dyes are specifically designed for multicolor techniques;characterized by an extremely large stoke’s shift between excitation and emission maxima. This dye is especially well suited for excitation by argon lasers or other short wavelength excitation light. This also means, that it can be excited with the same light source or filter arrangement than fluorescein and other widely used dyes as well as other Mega dye. Due to the different emission wavelength several different labels can be detected independently in the same experiment. Due to the small size of the Mega-labels and the direct conversion of excitation light into emission without using a FRET mechanism we foresee a variety of possible applications including DNA sequencing and FISH microscopy.
