Used in immunological research to study Siglec-10 mediated inhibitory signaling pathways, particularly in the context of immune cell regulation and cancer immunotherapy. The aldehyde (CHO) group enables site-specific conjugation to carrier proteins or surfaces, making it valuable for developing glycan arrays, diagnostic tools, and targeted therapeutics that modulate sialic acid-Siglec interactions. Its application extends to understanding immune evasion mechanisms employed by tumors and designing biologics that block suppressive signals in the tumor microenvironment.
