Ruthenium PEG Biotin is one of Nanocs Ruthenium Probes that can be used to detect avidin or streptavidin. Ruthenium is a transition metal and our specially synthesized complex has high luminescence. Upon excited at UV light, it emits strong red fluorescent photons. Compare to regualr organic fluorescent dyes, ruthenium based fluorophores have large stoke shift, exceptional photo-stability and longer fluorescent life time. Therefore, ruthenium tag is useful in time-gated fluorescent life time measurement, in confocal and two-photon imaging. More notably, rutheinum (II) complex is the most efficient electrochemiluminescent (ECL) that had been discovered so far. Nanocs has developed a number of ruthenium luminescent probes that can be used to label biomolecules, such as proteins, antibodies or nucleic acids. Our Ruthenium biotin probe can also be used to detect and imaging molecular and cellular components via its high affinity toward avidin or streptavidin. PEG linker between ruthenium and biotin offers high water solubility and good biocompatibility for using in probing biological systems.
