Allgemeine Beschreibung
Fluoresceinamine, isomer I belongs to the class of derivatized fluoresceins.
Anwendung
Fluoresceinamine, isomer I is suitable for use in a specific and sensitive spectrophotometric method for determining nitrite. It has been used to fluorescently tag nanoparticles through a competitive carboxyl-amine coupling reaction to visualize nanoparticle internalization.

Point mutants of three unrelated antifluorescein antibodies were constructed to obtain nine different single-chain Fv fragments, whose on-rates, off-rates, and equilibrium binding affinities were determined in solution. Additionally, activation energies for unbinding were estimated from the temperature dependence of the

We have studied the characteristics of binding of the polycation poly-L-lysine to the schistosome surface. Two consequences of this binding were measured: (a) tegumental damage, as assessed by the uptake of the DNA binding stain Hoechst 33258, and (b) the

The protective efficacy of sodium hyaluronate (Na-HA) on the corneal endothelium against the damage induced by sonication was investigated using enucleated rabbit eyes and Na-HA fluorescence labeled with 5-aminofluorescein (FA-HA). The anterior chamber was reformed by injecting a 1% solution

Hyaluronan (HA) is a highly hydrated polyanion, which is a network-forming and space-filling component in the extracellular matrix of animal tissues. Confocal fluorescence recovery after photobleaching (confocal-FRAP) was used to investigate intramolecular hydrogen bonding and electrostatic interactions in hyaluronan solutions.

Physico-chemical and topographical cues allow to control the behavior of adherent cells. Towards this goal, commercially available cell culture carriers can be finished with a laterally microstructured biomolecular functionalization. As shown in a previous study [Biomacromolecules 4 (2003) 1072], the

Dear manager, I want to ask you 2 questions about this product. 1. Is it a flurescence dye? Can you show me its adsorption or emission spectrum? 2. Is the amine group reactive?
1 answer-
Yes, Fluoresceinamine, isomer I is classified as belonging to a group of derivatized fluorosceins. The product is fluorescent. Although no quality control testing is performed to check for excitation and emission, the dye is expected to excite around 490 nm and emit around 520 nm.
As the H2N- group is not acetylated or protonated, the amine group can be considered reactive. There is literature available stating Fluoresceinamine, isomer I can be covalently bound to human serum albumin.
