Biocytin TMR

CF®488A is a superior green fluorescent dye


  • Minimally charged, for less non-specific binding than Alexa Fluor® 488
  • Narrower emission spectrum for less bleed to red
  • Very photostable
  • Compatible with super-resolution imaging by TIRF
  • Highly water soluble and pH-insensitive


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.


Stock solutions may be prepared in DMF or DMSO.


CF® dye biocytin is available in the following colors: CF®488A, CF®568, CF®594, and CF®640R.
