Biocytin TMR, CF® 488A Dye
Supplier: Biotium
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.
Upozornení: Store at –20 °C, protected from light.
