Description

Drosulfakinin Ii CAS NO 117457-91-7 is a synthetic neuropeptide analog, a crucial research tool for studying insect neuroendocrinology and behavior. This compound matters for its role in investigating sulfakinin signaling pathways, which are involved in regulating feeding, digestion, and satiety in Drosophila and other insects. It is primarily needed by researchers in academic institutions, biotechnology firms, and agrochemical R&D departments focused on insect physiology and the development of novel pest management strategies.

Application

• Neuroscience Research: Fundamental studies on sulfakinin receptor binding, signal transduction, and neural circuit modulation in insect models.
• Insect Physiology Studies: Investigation of peptide hormone functions related to feeding behavior, gut motility, and metabolic regulation.
• Agrochemical Discovery: Target validation and screening in the development of next-generation, peptide-based insect control agents.
• Comparative Endocrinology: Research into the evolutionary conservation of neuropeptide systems across species.
• Biochemical Assay Development: Used as a standard or tracer in receptor-ligand binding assays and immunoassays.
• Academic & Pharmaceutical R&D: Serves as a critical reagent for basic and applied research in neurobiology and endocrinology.
