Atto Rho11 Biotin is a new rhodamine dye 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. Biotin conjugates can be used in applications like ELISA or immunohistochemistry, in situ hybridization, flow cytometry and others, to identify streptavidin, avidin, or extravidin-conjugates.

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...

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...
