This recombinant monoclonal antibody is designed as a research-grade biosimilar to ROSE-12, targeting CTLA4 (Cytotoxic T-Lymphocyte Associated protein 4), a critical immune checkpoint receptor expressed primarily on T cells. CTLA4 functions as a negative regulator of T cell activation by competing with the co-stimulatory receptor CD28 for binding to B7 ligands (CD80/CD86) on antigen-presenting cells. By delivering inhibitory signals, CTLA4 maintains immune homeostasis and prevents autoimmunity. Dysregulation of CTLA4 signaling is implicated in various autoimmune disorders, including rheumatoid arthritis, type 1 diabetes, and inflammatory bowel disease, while its pathway is also exploited by tumors to evade immune surveillance.
ROSE-12 is an established research antibody widely used in immunology studies to investigate CTLA4 expression, localization, and function in immune regulation. This biosimilar provides researchers with a reliable tool for exploring immune checkpoint mechanisms, T cell biology, and the role of CTLA4 in cancer immunology and autoimmune disease pathogenesis. It supports various experimental approaches aimed at understanding immune modulation and developing therapeutic strategies.
