General description

Wheat germ lectin (WGA) from Triticum vulgaris exists as a homodimer and has multiple N-acetyl glucosamine (GlcNAc) binding sites. It is resistant to protein denaturation agents and is used for the detection of O-GlcNAc proteins. WGA binding to N-glycolylneuraminic acid (Neu5Ac) may modulate pro-inflammatory immune response.

Application

Lectin from Triticum vulgaris (wheat) has been used:
  • in lectin binding assay of samples from intrauterine stages of filarial parasites
  • in the histological studies of mice myocytes
  • for the generation bead-biotin-WGA complex with Dynabeads® M-280 Streptavidin magnetic beads for lectin magnetic separation of Toxoplasma gondii oocytes from water samples

Biochem/physiol Actions

WGA is not blood group specific but has an affinity for N-acetyl-β-D-glucosaminyl residues and N-acetyl-β-D-glucosamine oligomers. WGA contains no protein-bound carbohydrate.

Packaging

Package size based on protein content.

Physical form

Contains sodium citrate

Preparation Note

Conjugates are prepared from affinity purified lectin.
