Home / Products / Lectins and Glycobiology Reagents / Lectins / Amaranthus Caudatus Lectin (ACL, ACA) Amaranthus Caudatus Lectin (ACL, ACA) This lectin is a 66 kDa to 70 kDa dimer composed of two subunits of about 35 kDa. Four bands are resolved by isoelectric focusing. Unlike most lectins, ACL binds best in mildly acidic conditions. Although this lectin preferentially binds to oligosaccharides containing the galactosyl (β-1,3) N-acetylgalactosamine structure (T-antigen), tissue staining patterns are markedly different than those obtained with either peanut agglutinin or Jacalin. Amaranthus caudatus lectin also appears to tolerate sialic acid substitution at the 3 position of galactose in the “T” antigen. There are no products matching the selection.
