Description

Rhodamine 800 is a near-infrared fluorescent dye.

In Vitro

Rhodamine 800 has different optical absorption spectra in various organic solvents and in aqueous solution in the visible and near-infrared regions. The absorption maximum at 683 nm in acetone shifts to 696 nm in DMSO without a significant change of the overall spectral profile. The fluorescence intensity of Rhodamine 800 varies markedly with the solvent, and decreases to less than one-fifth when the solvent is changed from acetone to water without a significant change of the emission peak[1].

Kinase Assay
[2]

Rhodamine 800 (Rh800) and indocyanine green (ICG) are dissolved in PBS and their concentrations are set to 40 nM. To 3 mL of Rhodamine 800 solution (40 nM/PBS), 100 μL of p-sulfonatocalix[n]arenes (S[n]) (1 mM) is added. To this solution, microliter aliquots of acetylcholine (ACh) (350 mM) are added under stirring. After 2 min stirring, fluorescence spectra are measured. For the competitive fluorophore displacement by other neurotransmitters, amino acids, ammonium chloride, and choline, similar procedure as the above method is applied[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
