Description

Leucokinin Iv CAS NO 104958-72-7 is a synthetic peptide analog of the insect neuropeptide leucokinin, identified by the CAS registry number 104958-72-7. This compound is of significant interest in biochemical research for its role in studying diuretic and myotropic functions in insect physiology. It serves as a critical tool for researchers and developers in the fields of entomology, insect neurobiology, and agrochemical discovery, particularly for investigating novel pest control strategies and fundamental biological signaling pathways.

Application

• Insect Neurobiology Research: Fundamental studies on neuropeptide signaling, receptor binding, and physiological effects in various insect species.
• Agrochemical R&D: Investigation of potential novel modes of action for the development of next-generation, selective insect growth regulators or biopesticides.
• Physiological Studies: Research into diuretic and myotropic (muscle-contracting) functions to understand fluid homeostasis and muscle control in insects.
• Comparative Endocrinology: Used as a reference standard in studies comparing peptide hormone systems across different invertebrate and vertebrate species.
• Academic & Institutional Research: A key reagent for universities and research institutes focused on peptide chemistry, endocrinology, and integrated pest management (IPM) strategies.

Quality Control

Our Leucokinin Iv is produced under stringent conditions to ensure high purity and batch-to-batch consistency, suitable for sensitive research applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and peptide content. We adhere to rigorous internal quality standards and can support development work requiring specific analytical protocols. Certificates of Analysis (COA) are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. This product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and hydrolysis. For long-term storage, consider keeping the product under an inert atmosphere.
