    CCK-BR Antibody (4A5) is a mouse monoclonal IgG1 antibody that detects CCK-BR in mouse, rat, and human samples through immunofluorescence (IF) and immunohistochemistry with paraffin-embedded sections (IHCP). CCK-BR, or cholecystokinin B receptor, plays a crucial role in mediating the physiological effects of its ligands, gastrin and cholecystokinin, which are vital for digestive processes and appetite regulation. Anti-CCK-BR antibody (4A5) recognizes a receptor predominantly located in the gastrointestinal tract and the central nervous system, where CCK-BR influences various functions such as gastric acid secretion, smooth muscle contraction, and neurotransmission related to satiety and anxiety. The presence of CCK-BR in these locations underscores its importance in both digestive health and neuroregulation, making CCK-BR a significant target for therapeutic interventions in gastrointestinal and central nervous system disorders. CCK-BR monoclonal antibody (4A5) serves as an essential tool for researchers aiming to explore the intricate signaling pathways involving CCK-BR and its potential implications in health and disease.
