Rabbit anti Human Substance P antibody recognizes human Protachykinin-1, also known as PPT. Protachykinin-1 is a 129 amino acid ~15kDa tachychinin involved in the excitation of neurons. Protachykinin-1 can be cleaved into a number of chains including substance P, neurokinin A, neuropeptide K, neuropeptide γ and c-terminal flankning peptide. Rabbit anti Human Substance P antibody recognizes an epitope withing the substance P region of the molecule. There are potentially four isoforms of Protachykinin-1 (α - δ) formed by alternative splicing, all containing the substance P peptide region (UniProt: P20366).

Rabbit anti Human Substance P antibody stains substance P secreting cells of the external median eminance of the hypothalamus and specific cells of the GI tract. Rabbit anti Human Substance P antibody also stains neuronal structures.
