Substance P is a bioactive 11-amino acid peptide (Arg-Pro-Lys-Pro-Gln-Gln-Phe-Phe-Gly-Leu-Met-amide) first isolated in 1931 from brain and intestine. The peptide is involved in many physiological processes including pain modulation, smooth muscle contraction, blood pressure control, kidney function and water homeostasis.{954,1041,10154} Substance P is widely distributed in numerous tissues and body fluids including the central and peripheral nervous system, gastrointestinal tract, respiratory tract, visual system and circulatory system.{10154} Cayman’s Substance P ELISA is a competitive assay that provides accurate measurements of Substance P with a working range of 3.9 to 500 pg/ml, typically with an IC50 (50% B/B0) of ~30 pg/ml and IC80 (80% B/B0) of ~8 pg/ml. Inter- and intra-assay CV’s of less than 20% can be achieved at most concentrations of the standard curve. Due to cross-reactivity with Hemokinin-1, we do not recommend this ELISA to measure Substance P in serum and plasma samples.
