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.
