α-Glucosidase
from yeast overproducer, multifunctional, lyophilizate
Recombinant glucosidase, that hydrolyzes 1,4-linked α-D-glucose residues
with release of α-D-glucose.
Application
Use α-Glucosidase in diagnostic tests for the determination of α-amylase
and pancreatic α-amylase activity according to the recommendations of the
International Federation of Clinical Chemistry and Laboratory Medicine (IFCC).
It catalyzes the 100% liberation of p-nitrophenol residues from the amylase
substrate EPS (Catalog No. 10 880 078 103) once it has been cleaved by
α-amylase.
Benefits
Use this recombinant enzyme in your amylase reagent mix and rely on the
100% chromophore liberation and the proven diagnostic quality of this
product.
