Glyko® β(1-3,4)-Galactosidase [GKX-5013]

Price:
$ 260.00

Description

Hydrolyzes non-reducing terminal galactose β(1-3) and β(1-4) linkages. Can be used in conjunction with other β-galactosidases for exoglycosidase sequencing.

Applications:
The enzyme has applications in the analysis of a wide variety of glycoconjugates. It is particularly useful for ensuring the complete removal of β(1-3) and β(1-4)-linked non-reducing terminal galactose residues of oligosaccharides. Gal β(1-6) GlcNAc is hydrolyzed more slowly, however this linkage is not normally encountered in native complex glycans. This activity towards β(1-3) and β(1-4)-linked galactose contrasts with that of our other β-galactosidases (e.g. from S.pneumoniae, GKX-5014, or Jack bean, GKX-5012) which exhibit a preference for Gal β(1-4), and cleave the Gal β(1-3) linkage relatively slowly, if at all. Used in conjunction, these enzymes provide a powerful means to determine linkage positions of non-reducing β galactose residues.
