Biotium offers an array of fluorescent cytosolic tracers for various cell types and applications:
ViaFluor® SE Cell Proliferation Dyes are non-toxic and can be used to stain cells for long-term, fixable cell tracing for flow or microscopy.
CFDA and
Calcein AM are membrane-permeant esterase substrates with green fluorescence. CF® Dye-labeled molecules such as
Dextran and
BSA can be used to observe endocytosis. Polar tracers used to trace neurons and cell junctions include CF® Dye-labeled
Biocytin,
Hydrazide, and
Fluoro-Gold™.
