(4-Methylumbelliferyl)-N-acetyl-α-D-neuraminic acid sodium salt Usage And Synthesis
Description
4-Methylumbelliferyl-N-acetyl-α-D-neuraminic acid is a fluorogenic substrate of neuraminidases. 4-Methylumbelliferyl-N-acetyl-α-D-neuraminic acid is cleaved by neuraminidases to release the fluorescence moiety 4-methylumbelliferyl (4-MU). 4-MU fluorescence is pH-dependent with excitation maxima of 320 and 360 nm at low (1.97-6.72) and high (7.12-10.3) pH, respectively, and an emission maximum ranging from 445 to 455 nm, increasing as pH decreases. 4-Methylumbelliferyl-N-acetyl-α-D-neuraminic acid has been used to quantify neuraminidase activity in mammalian cells and clinical isolates of influenza virus.
