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
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.
Bovine Serum Albumin CF® Dye Conjugates
CF® dye bovine serum albumin (BSA) are 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
Cholera toxin B subunit is used for tract-tracing in neurological research, targeting GM1 ganglioside binding and retrograde transport. CF® dyes offer exceptional brightness and photostability.
Transferrin (human) CF® Dye Conjugates
Transferrin is a glycoprotein with homologous N-terminal and C-terminal iron-binding domains that binds up to two Fe(III) atoms for delivery to vertebrate cells through receptor-mediated endocytosis.
