5-TAMRA C6 maleimide

5-TAMRA C6 maleimide is an excellent replacement for tetramethylrhodamine-5-maleimide. It selectively reacts with thiol groups of peptides, proteins and other biological molecules (such as thiol-modified oligonucleotides and small thiol-containing organic molecules). It might give higher conjugation yield than tetramethylrhodamine-5-maleimide under similar conjugation conditions. 5-TMR C6 maleimide has the spectral propertied identical to those of tetramethylrhodamine-5-maleimide, thus all the instrument settings of the tetramethylrhodamine-5-maleimide would be applicable to the applications of 5-TMR C6 maleimide conjugates.
