Substance P is an 11-amino acid neuropeptide belonging to the tachykinin family that functions as a neurotransmitter and neuromodulator in the central and peripheral nervous systems. It plays key roles in pain transmission, inflammation, and stress responses by binding to neurokinin-1 receptors. Substance P is widely distributed throughout the nervous system and is particularly concentrated in sensory neurons, where it mediates nociceptive signaling and contributes to neurogenic inflammation. Its involvement in various physiological processes makes it an important target for neuroscience research and therapeutic development.
The Rat Substance P ELISA Kit (CSB-E08358r) is designed for quantitative measurement of SP in rat samples using a sandwich assay principle. This kit works with multiple sample types including serum, plasma, cell culture supernatants, and tissue homogenates with a detection range of 6.25-400 pg/mL and sensitivity of 1.56 pg/mL. The assay requires 50-100 μL sample volume, operates at 450 nm detection wavelength, and can be completed within 1-5 hours.
