Texas Red® azide *Single Isomer*

Texas Red® azide is an excellent alkyne-reactive fluorescent reagent for labeling alkyne-containing biological molecules through the well known click chemistry. 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 Texas Red® azide conjugates.
