Recombinant, Arthrobacter ureafaciens α2-3,6,8,9-Neuraminidase expressed in E. coli. Catalyzes the hydrolysis of all non-reducing terminal sialic acid residues from complex carbohydrates and glycoproteins. High concentrations of this sialidase and prolonged periods of incubation result in the additional cleavage of branched sialic acids. This enzyme is found as two active species of MW 60000 and 69000.
Warning
Toxicity: Harmful (C)
Unit Definition
One unit is defined as the amount of enzyme that will catalyze the release of 1 µmol of methylumbelliferone from 2ʹ-(4-methylumbelliferyl)-α-D-N-acetylneuraminic acid per min at 37°C, pH 5.0. (Note: 1 mU = 1 milliunit).

Influenza and other respiratory viruses, 13(6), 593-602 (2019-08-09)
The influenza A virus (IAV) binds to α-2,3- and α-2,6-linked sialic acid (SA) receptors expressed by Madin-Darby canine kidney (MDCK) cells. The receptor distribution may therefore be important in regulating IAV propagation. Serum-free medium (SFM) avoids variability in conventional culture
To compare goblet cell (GC) number and area in the covered superior (SB) versus exposed temporal (TB) bulbar conjunctiva in control versus aqueous tear deficient eyes (ATD) and evaluate correlation with tear MUC5AC protein. SB and TB impression cytology performed
