Description:
Hyaluronic Acid is labeled with both rhodamine (Ex/Em wavelength 552/575 nm) and fluorescein (Ex/Em wavelength 494/518 nm). The rhodamine used in all of polysaccharide products is 5/6-carboxy-tetramethyl- rhodamine, (5/6-TAMRA).
Purity: >95% lyophilized powder.
Degree of substitution: 1 mol % substitution for each dye and at least one rhodamine and one fluorescein molecule per polymer.
