Sialylglycopeptide is widely used in biochemical research, particularly in studies related to glycobiology and immunology. It serves as a valuable tool for investigating cell surface interactions, especially those involving sialic acid residues. This compound is instrumental in understanding cell signaling pathways, immune responses, and the role of glycosylation in disease mechanisms. Additionally, it is utilized in the development of diagnostic assays and therapeutic agents targeting specific carbohydrate-protein interactions. Its application extends to the study of viral entry mechanisms, as sialic acid is often a key receptor for viruses, making it relevant in virology and vaccine research.
