CF® Dye Biocytin
CF® dye biocytin is a cell-impermeant, fixable polar tracer that is a conjugate of CF® dye and biotin with an aldehyde-fixable primary amine. 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® Dye Hydrazide
Fluorescent CF® dye hydrazides are bright, extremely water-soluble, nontoxic molecules, useful as aldehyde-fixable cell tracers. They can also be used to label aldehyde or ketone groups of polysaccharides, carbohydrates or glycoproteins.
Bovine Serum Albumin CF® Dye Conjugates
Bright and photostable fluorescent BSA conjugates for applications in which well-defined molecular weight fluid phase tracers are needed. These applications include studying the rate of endocytosis and exocytosis and following vesicle trafficking.
Cholera Toxin Subunit B CF® Dye Conjugates
Binds GM1 ganglioside in lipid rafts and is used as a retrograde neuronal tracer for live imaging or on fixed cells.
Transferrin (human) CF® Dye Conjugates
Labeled human transferrin is used for microscopic studies of the endosomal pathway and/or transferrin uptake studies.
