CF® Dye Hydrazide
Our CF® dye hydrazides are bright, extremely water-soluble and nontoxic. These properties make the dyes excellent fixable polar tracers for neurons, or for gap junction studies.
CF® Dye Biotin
Potential applications of Biotin-CF® dye include detection of biotin binding sites and the degree of biotinylation of proteins, and for the measurement of avidin and streptavidin in crude biological samples. In addition, biotin-CF® dye can be used as a polar tracer by microinjection to study the morphology of cells.
