  • Applications

    Locustapyrokinin protein, Locusta migratoria (CAS 132293-87-9) is primarily used as a biochemical research reagent for studying insect neuropeptide signaling and pyrokinin receptor interactions. It serves as a standard in proteomics/peptidomics workflows and as a ligand in receptor characterization assays. In agricultural science it is evaluated in pest-control research as a potential target or mimic of neuropeptide pathways in Locusta species. It can function as an educational tool in neurobiology research and as a reference in assay development related to insect physiology, with practical use contingent on local regulations and formulation constraints.
