Description

Pyrrhocoris Defensin is a specialized antimicrobial peptide originally isolated from the firebug, *Pyrrhocoris apterus*. This compound matters for its potent and selective activity against a range of Gram-positive bacteria, making it a valuable tool for research into novel antibiotic mechanisms and therapeutic development. It is primarily needed by researchers and developers in the pharmaceutical, biotechnology, and life science sectors for applications in antimicrobial studies, peptide engineering, and as a biochemical standard.

Application

• Antimicrobial Research: Used as a reference standard in studies investigating the mechanism of action of insect-derived defensins against bacterial pathogens.
• Peptide Drug Discovery: Serves as a lead compound or structural template for the development of new antibiotic peptides with enhanced stability and efficacy.
• Biochemical Assays: Employed in in vitro assays to screen for antimicrobial activity and to study host-pathogen interactions.
• Academic & Institutional Research: Utilized in university and institutional labs for fundamental research in immunology, entomology, and molecular biology.
• Biotechnology Reagent: Acts as a high-purity biochemical reagent in the production of diagnostic kits or research-grade materials.

Quality Control

Our Pyrrhocoris Defensin is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and MS for identity confirmation, to ensure it meets the high standards required for research applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and other critical parameters is available upon request to support your quality assurance and regulatory documentation needs.

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 before opening to minimize moisture uptake. For long-term storage, consider under an inert atmosphere.
