Protein Labeling Reagents
Biotium CF633 Hydrazide
Our CF dye hydrazides are bright, extremely water-soluble and nontoxic. These properties make the dyes excellent fixable polar tracers for microinjection into cells. Hydrazides also can be used for labeling aldehyde or ketone groups, however, for this application we recommend using the more reactive CF dye aminooxy forms. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Far-red fluorescent CF633 dye has excitation/emission at 630/650 nm.

Medchemexpress LLC Sulfo-Cy5.5 Azide | 1955527-41-9 | C44H50N6O13S4 | 5 MG
Sulfo-Cy5.5 Azide is a click chemistry reagent that contains an azide group. It is a water-soluble dye with excitation at 673 nm and emission at 707 nm. It is designed to label sensitive molecules like peptides, proteins, and oligonucleotides. The azide group allows it to undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing alkyne groups, and ring strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing DBCO or BCN groups.

Biotium CF568 Biocytin
Fluorescent biocytin conjugates are cell-impermeant, fixable polar tracers with biotin and an aldehyde-fixable primary amine groups. Polar tracers are commonly used to investigate cell-cell and cell-liposome fusion as well as membrane permeability and transport through gap junctions or cell uptake during pinocytosis. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Red fluorescent CF568 dye has excitation/emission at 562/583 nm.
