Chemical structure of 4-MUNANA (sodium salt)

GC42448

4-MUNANA (sodium salt)

Also known as sodium N-[(2R,3R,4S,6S)-6-carboxy-4-hydroxy-6-(4-methyl-2-oxochromen-7-yl)oxy-2-[(1R,2R)-1,2,3-trihydroxypropyl]oxan-3-yl]ethanimidate

4-MUNANA (sodium salt) is a fluorescent substrate for neuraminidase activity assays· When 4-MUNANA is hydrolyzed by the enzyme, it releases the fluorophore 4-methylumbelliferyl (4-MU), which has an excitation maximum at 365nm and an emission maximum at 450nm
