Amaranthus caudatus Lectin (ACL/ACA) - Pure

Affinity-purified Amaranthus caudatus Lectin (ACL/ACA) is a dimeric glycoprotein composed of two subunits. It preferentially binds to oligosaccharides containing the galactosyl disaccharide Galβ3GalNAc and can tolerate sialic acid substitutions at the 3 positions of galactose in the "T" antigen. While ACL does not exhibit specificity for blood groups, it shows a higher affinity for type O erythrocytes compared to types A and B.

Recommended Usage: Recommended dilution is 0.5 – 10 µg / ml. Less than 1 µg/ml will agglutinate human, rabbit, goat, sheep, rat, guinea pig erythrocytes.

Storage Instruction: To prevent degradation and avoid repeated freeze-thaw cycles, aliquot your product into small, single-use volumes and store them at -20°C

Application

Histochemical probe for proliferating colonic epithelial cells, T-antigen probe. Glycan profiling, Immunocytochemistry, Cell typing, Bioconjugation, Blotting, Glycobiology.
