Description

Red Pigment-Concentrating Hormone (RPCH) is a specialized neuropeptide hormone that plays a critical role in the physiological color change and pigment migration processes in crustaceans and certain insects. This high-purity compound is essential for research and development in comparative endocrinology and as a key biochemical tool for studying pigment cell regulation. It serves the needs of biochemical suppliers, academic research institutions, and biotechnology companies focused on invertebrate physiology, aquaculture, and novel biosensor development.

Application

• Comparative Endocrinology Research: Fundamental studies on the hormonal control of pigmentation and color adaptation in crustaceans (e.g., shrimp, crabs, crayfish) and insects.
• Aquaculture and Fisheries Science: Investigating stress responses, physiological markers, and growth regulation in commercially important shellfish species.
• Biochemical Reagent Production: Serves as a standard or active ingredient in the formulation of diagnostic kits and research assay systems for endocrinological studies.
• Neuropeptide and Signal Transduction Studies: Used as a model peptide to investigate G-protein-coupled receptor (GPCR) pathways and intracellular signaling cascades.
• Development of Bioassays: Acts as a reference compound in bioassays designed to screen for environmental endocrine disruptors or to evaluate the efficacy of feed additives.
• Teaching and Reference Standard: Provides a high-purity standard for university-level teaching laboratories and quality control in related biochemical manufacturing.

Quality Control

Our Red Pigment-Concentrating Hormone is produced and controlled under a strict quality management system. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation and mass spectrometry (MS) for structural verification. We ensure compliance with high-purity biochemical standards suitable for research applications. A comprehensive Certificate of Analysis (COA) detailing purity, peptide content, and solvent residues is provided with every shipment.

Storage

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