Used in research and development for inflammatory diseases and transplant rejection due to its ability to target ICAM-1 (CD54), a protein involved in leukocyte adhesion and migration. By blocking ICAM-1, it modulates immune cell activation and reduces inflammation. Investigated for potential therapeutic use in autoimmune conditions such as psoriasis, rheumatoid arthritis, and inflammatory bowel disease. Also employed as a reference standard in immunoassays and bioanalytical studies to evaluate binding affinity and functional activity of anti-ICAM1 antibodies. Supports drug discovery and quality control in biopharmaceutical development.
