6-ROX C2 maleimide is an excellent thiol-reactive ROX probe that can be used to develop new ROX bioconjugates。 It selectively reacts with thiol groups of peptides, proteins and other biological molecules (such as thiol-modified oligonucleotides and small thiol-containing organic molecules)。 6-ROX C2 maleimide has the spectral properties identical to those of 6-ROX conjugates, thus all the instrument settings of the 6-ROX probes would be applicable to the applications of 6-ROX C2 maleimide conjugates。 Compared to the commonly used 6-ROX acid and 6-ROX SE, 6-ROX C2 maleimide is much more stable。
