Description

General description

A substrate for uridyltransferase that catalyzes the reaction of UDP-glucose with galactose-1-phosphate to form glucose-1-phosphate and UDP-galactose. Higher levels of galactose-1-phosphate are reported in patients with galactosemia.

Free of glucose-1-phosphate and related sugar nucleotides that tend to contaminate isolated material.

Preparation Note

Following reconstitution, aliquot and freeze (-20°C). Aqueous stock solutions are stable for at up to 3 weeks at -20°C.
