Application
Atto Rho11 maleimide is a new rhodamine dye featuring a functionality for coupling to bio-molecules such as DNA, RNA, proteins etc. The label shows very high fluorescence efficiency and exceptionally high photostability. The dye is moderately hydrophilic. ATTO Rho11 is a cationic dye. After coupling to a substrate the label carries a net electrical charge of +1. Maleimides are well suited for coupling to thiol groups. This is similar to iodacetamides, but maleimides react more selectively with thiols. They do not show significant reaction with histidine or methionine. Hydrolysis of maleimides to a mixture of isomeric nonreactive maleamic acids can compete significantly with thiol modification, particularly above pH 8. Maleimides may be used for labeling of amines, which usually requires a higher pH than reaction of maleimides with thiols.

Light in the near-infrared (NIR) region between 700-900 nm can penetrate deep into living tissue, thereby offering a unique opportunity to use near-infrared fluorescence (NIRF) imaging techniques to detect and visualize fluorescent probes in-vivo. In the past few years, many

Polymeric nanoparticles have been widely applied to oral delivery of protein drugs, however, few studies focused on the systematical elucidation of the size-dependent oral absorption mechanism with well-defined polymeric nanoparticles.

In vivo fluorescence imaging uses a sensitive camera to detect fluorescence emission from fluorophores in whole-body living small animals. To overcome the photon attenuation in living tissue, fluorophores with long emission at the near-infrared (NIR) region are generally preferred, including
