rhodaminen
Rhodaminen refers to a family of synthetic fluorescent dyes based on the xanthene chromophore, collectively known as rhodamines. These dyes are typically cationic and water-soluble, exhibiting bright fluorescence in the visible range and good photostability, which makes them popular as labels in biochemical and biomedical applications.
Chemically, rhodamines consist of a tricyclic xanthene core with amino substituents, such as diethylamino groups. Variants
Spectral properties vary by dye. Rhodamine B and rhodamine 6G typically absorb around 520–565 nm and emit
Primary uses include labeling biomolecules such as antibodies, nucleic acids, and proteins for fluorescence microscopy, flow
Common derivatives include rhodamine B, rhodamine 6G, rhodamine 123, and rhodamine 110; many rhodamine dyes are
Safety: rhodamine dyes may be irritants and can be hazardous if ingested or inhaled; appropriate handling, disposal,
