Immobilised D-Galactose agarose enables purification of lectins, galactosidases and other galactose-binding molecules. The immobilised D-galactose is a beaded agarose affinity resin that enables purification of agglutinins, lectins, toxins, and other galactose-binding proteins, N-acetylgalactosamine-binding proteins or carbohydrate-binding proteins.

• Ligand: thio-alpha-D-galactose
• Synonyms: thio-alpha-gal, thio-gal
• Support: crosslinked 6% beaded agarose
• Binding capacity: at least 20 mg jacalin per milliliter of settled resin
• Format: 50% resin slurry in 0,02% sodium azide
• Storage: 4 °C

This purification method is milder and/or more specific than other methods, allowing protein recovery in a manner that preserves activity for downstream applications.

Applications include human alpha-galactosidase A purification, C-type lectin purification, E. coli heat labile enterotoxin purification, cholera toxin (CT) purification.
