Triticum vulgaris lectin (WGA) is widely used in biological and medical research due to its ability to bind specifically to N-acetylglucosamine and sialic acid residues. It is commonly employed in cell biology to study cell surface glycoproteins and glycolipids, aiding in the identification and visualization of specific carbohydrate structures on cell membranes. WGA is also utilized in histochemistry and immunohistochemistry to label and detect glycoconjugates in tissue samples, providing insights into cellular and tissue organization. Additionally, it serves as a tool in neuroscience for tracing neuronal pathways, as it binds to and is transported along neuronal membranes. In biotechnology, WGA is used in affinity chromatography to purify glycoproteins and other carbohydrate-containing molecules. Its applications extend to cancer research, where it helps in studying changes in glycosylation patterns associated with tumor cells.
