The rSRL is a carbohydrate-binding protein (Lectin) derived from Sclerotium rolfsii. The rSRL gene product is expressed in Escherichia coli. This lectin preferably binds to two types [GlcNAcβ(1-2)Man, Galβ(1-3)GalNAc] of glycan epitopes by its two distinct carbohydrate-binding sites.
Biotin is covalently linked to the protein surface. Resulting band shift caused by biotinylation is checked by SDS-PAGE. (Unbiotinylated band is mostly not observed.) The rSRL-Biotin shows significant interaction with agalacto human transferrin (hTF) possessing [GlcNAcβ(1-2)Man] glycan epitopes by lectin-ELISA analysis. According to the lectin-blotting analysis, the rSRL-Biotin specifically binds to β(1-2)GlcNAc-terminated hTF but not to non-β(1-2)GlcNAc-terminated glycoproteins such as hTF, asialo hTF and bovine RNase B.

Store at -20°C to -80°C. Avoid repetitive freezing and thawing. After thawing the product, it’s recommended to store at 2-10°C with an additional preservative (e.g., 0.02-0.05% [w/v] sodium azide).
