5(6)-TAMRA azide Size:10mg The water soluble 5(6)-FAM PEG3The red fluorescent 5(6) TAMRA azide is an excellent alkyne reactive fluorescent reagent for labeling alkyne containing biological molecules through click chemitry. It has the spectral properties identical to those of TRITC conjugates. Click chemistry describes a class of chemical reactions that use bio orthogonal or biologically unique moities to label and detect a molecule of interest using a two step procedure. The two step reaction procedure
