TMR biocytin is a cell-impermeant, fixable fluorescent polar tracer that combines the tetramethylrhodamine (TAMRA) with biotin with an aldehyde-fixable primary amine


  • A cell impermeant, fixable fluorescent polar tracer to study cellular and neuronal uptake, fusion and transport processes
  • λAb / λEm: 544 nm / 571 nm
  • Dark Red solid
  • Soluble in DMF or DMSO
  • Store at -20°C


TMR biocytin is a cell-impermeant, fixable polar tracer that combines the tetramethylrhodamine (TAMRA) with 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.
TMR biocytin proved to be an effective neuronal tracer in live tissue when applied by electroporation (Ref. 1) .
