Succinylated wheat germ agglutinin (Succ-WGA) is affinity purified from the native wheat germ agglutinin (WGA). It is dimeric at pH as low as 5 and dissociates at pH lower than 4.5. Succ-WGA agglutinates rabbit erythrocytes at a minimal concentration of about 2g/ml, and agglutinates human erythrocytes of blood groups A, B, and O types. The solubility of Succ-WGA is around 100 times higher than the unmodified lectin at neutral pH. Ulike native WGA, Succ-WGA does not bind to sialic acid residues but retains its specificity towards N-acetylglucosamine. The use of conjugates of the native WGA and the succinylated allows to distinguish between sialylated glycoconjugates and others N-acetylglucosamine structures. See other Succ-WGA conjugates.Biotin is a small molecule involved in a wide range of metabolic processes. This ligand forms a complex with Avidin and Streptavidin, resulting in the strongest non-covalent protein-ligand interaction known. Biotinylated Succinylated Triticum vulgaris Lectin (Succ WGA) has an appropriate amount of biotin bound to provide optimum detection characteristics when using an Avidin-HRP or Streptavidin-HRP conjugate. Biotinylated lectins allow for more sensitive detection in ELISA and Western-blotting applications.
