ATTO 490LS
ATTO 490LS 是一种新型荧光标记物,其特征是具有高达165nm的超大斯托克斯位移。 Thus the emission spectrum 是一种lmost completely separated from the absorption spectrum, making the dye highly suitable for multicolor experiments, in particular in combination with ATTO 488 and ATTO 514 . ATTO 490LS is very 亲水性, highly water soluble, and exhibits a relatively high 荧光量子产率, which is only slightly reduced on conjugation to 生物分子, e.g. proteins, even at high degrees of labeling (DOL).
ATTO 490LS 是一种n anionic dye. After conjugation to a substrate the dye carries a net electrical charge of -1. The fluorescence is excited most efficiently in the range 460 - 530 nm.
