Texas Red® maleimide *Single Isomer*

Texas Red® maleimide

Single Isomer

Texas Red® maleimide is an excellent thiol-reactive fluorescent reagent for labeling thiol-containing biological molecules (such as peptides, proteins and thiol-modified oligonucleotides). It selectively reacts with thiol groups of peptides, proteins and other biological molecules (such as small thiol-containing organic molecules). It has the spectral properties identical to those of Texas Red conjugates, thus all the instrument settings of the Texas Red conjugates would be applicable to the applications of TR C2 maleimide conjugates.
