Description
The rPSL1a is a carbohydrate-binding protein (Lectin) derived from Polyporus squamosus. The rPSL1a gene product is expressed in Escherichia coli. This lectin preferably binds to a [Siaα(2-6)Gal] glycan epitope (It very slightly interacts with lactose.). Consequently, rPSL1a exhibits a hemagglutination activity to a rabbit reticulocyte through the glycan binding to subsites and subunits of the lectin.
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 rPSL1a-Biotin shows significant interaction with human transferrin (hTF) possessing [Siaα(2-6)Gal] glycan epitopes by lectin-ELISA analysis. According to the lectin-blotting analysis, the rPSL1a-Biotin specifically binds to α(2-6)Sia-terminated hTF but not to unsialylated glycoproteins such as asialo hTF, agalacto hTF and bovine RNase B.

Storage
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).
