Description

Leucosulfakinin Ii CAS NO 106206-79-5 is a synthetic peptide analog of the endogenous insect neuropeptide sulfakinin, known for its role in regulating satiety and digestive functions. This compound is of significant interest for advanced research in insect physiology and the development of novel, species-specific pest management strategies. It is primarily utilized by researchers in entomology, agricultural science, and peptide chemistry for studying metabolic pathways and exploring next-generation biopesticides.

Application

• Fundamental Entomological Research: Used as a precise biochemical tool to study the role of sulfakinins in insect feeding behavior, gut motility, and energy homeostasis.
• Mode-of-Action Studies for Pest Control: Serves as a reference standard in assays designed to identify and validate novel molecular targets for insecticide development.
• Peptide Receptor Characterization: Employed in binding studies and functional assays to characterize sulfakinin receptors across various insect species.
• Physiological and Behavioral Assays: Applied in laboratory settings to investigate the effects on specific insect behaviors related to hunger and digestion.
• Biochemical Standard: Acts as a high-purity calibrant or control in analytical methods such as HPLC and mass spectrometry within research laboratories.
