Biotin-Substance P（Cat No.:I044255）is a biotinylated form of the neuropeptide Substance P, which is involved in pain transmission, inflammation, and neuroimmune signaling. The addition of a biotin moiety allows for high-affinity binding to streptavidin or avidin, enabling detection, purification, or immobilization in biochemical assays. Biotin-Substance P is widely used in receptor binding studies, imaging, and affinity-based applications to investigate the neurokinin-1 (NK1) receptor and related signaling pathways. Its labeled format provides a powerful tool for tracking Substance P interactions in neurobiology, pharmacology, and inflammatory disease research.
