Alpha-Galactosidase A Protein, Human (HEK293, His)

Alpha-Galactosidase A Protein, Human (HEK293, His), a recombinant human alpha-Galactosidase A produced in HEK293 cells, has a His tag at the C-terminus. Alpha-Galactosidase A Protein, Human (HEK293, His) is the lysosomal exoglycosidase responsible for the hydrolysis of terminal α-galactosyl residues from glycoconjugates and is the defective enzyme causing Fabry disease^[1].

alpha-Galactosidase A (α-GAL, also known as α-GAL A) is responsible for the breakdown of α-galactosides in the lysosome. Defects in human alpha-Galactosidase A lead to the development of Fabry disease, a lysosomal storage disorder characterized by the buildup of α-galactosylated substrates in the tissues. alpha-Galactosidase A is an active target of clinical research: there are currently two treatment options for Fabry disease, recombinant enzyme replacement therapy and pharmacological chaperone therapy^[2].

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
