Popular green fluorescent cell-permeable dye. Covalently couples via its succinimidyl group to intracellular molecules. The amine-reactive succinimidyl ester of 6-FAM acid is a common fluorescent derivatization reagent for covalently labeling peptides, proteins and nucleotides. Due to this covalent coupling reaction it can be retained within cells for extremely long periods and due to this stable linkage, once incorporated within cells the dye is not transferred to adjacent cells. Yields carboxyamides which are more resistant to hydrolysis than fluorescein conjugates prepared with FITC. Better retained in cells than fluorescein. Spectral data: lambdaex 496 nm| lambdaem 516 nm (Buffer pH 9.0).

Derivatives of 7-aminocoumarins are the most extensively utilized labeling reagents for preparing brightly blue fluorescent conjugates of proteins and nucleic acid. Labeled amino acids are detected with visible semiconductor laser fluorometry using second harmonic emission (415 nm) of the near-infrared semiconductor laser. Arginine, proline, serine and glycine have been detected with detection limits around 100 amol levels. The fluorescent-labelling better matches the excitation-wavelength of standard blue lasers than conventional fluorescein-isothiocyyanate.

Sulforhodamine 101 is a non-fixable red fluorescent dye used as a specific marker for astrocytes and an activity-dependent probe for monitoring regulated exocytosis. In addition to labeling astrocytes, it also labels myelinating oligodendrocytes. Has been reported to affect excitability of neurons and should therefore be used with caution. Key precursor used for preparing rhodamine 101 sulfonyl chloride (also called Texas Red). Spectral data: lambdaex 586 nm| lambdaem 605 nm in H2O and lambdaex 582-588 nm| lambdaem 601-609 nm in pH7 buffer.
