Substance P Antibody (SP-DE4-21) is a mouse monoclonal IgG1 antibody specifically designed to target Substance P, an 11-amino-acid neuropeptide belonging to the tachykinin family and also known as neurokinin-1 ligand. Substance P monoclonal antibody (SP-DE4-21) is raised against amino acids 1-11 of human Substance P. Substance P′s structure as an undecapeptide is crucial because its precise amino acid arrangement allows it to bind effectively to the neurokinin-1 (NK1) receptor, mediating essential physiological processes such as pain transmission, inflammation, and vasodilation. Anti-Substance P antibody (SP-DE4-21) reacts with Substance P and the protachykinin 1 precursor in mouse, rat, human, equine, and bovine species when used in immunofluorescence (IF) and immunohistochemistry with paraffin-embedded sections (IHCP), and does not cross-react with related tachykinins like neurokinin A, neurokinin B, or kassinin. Substance P monoclonal antibody (SP-DE4-21) aids researchers in exploring the peptide′s role in neurological and immunological functions, contributing to studies on pain mechanisms and inflammatory diseases. Understanding the structure of Substance P is important because any alterations can affect its interaction with receptors, influencing its biological activity and potential as a therapeutic target. Anti-Substance P antibody (SP-DE4-21) serves as a valuable tool for investigating the complex pathways involving tachykinins and their implications in health and disease.
