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

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.

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.
