What is APTS?
Chemical properties
Brownish Orange Solid
The Uses of APTS
APTS is a very useful green fluorescent dye for labeling glycoproteins or sugar molecules in general.
The Uses of APTS
Fluorescent label for glycoproteins and saccharides.
The Uses of APTS
APTS is a fluorescence reagent that has been demonstrated to have a high level of detection sensitivity for sugars The LOD for APTS-derivatized sugars has been shown to be 0.4 nM when using a 488 nm argon-ion laser. The multi-anionic nature of APTS makes it ideal for the studies of carbohydrate molecules and small hormone molecules by high resolution capillary electrophoresis.
