Description

Pyrrhocoricin CAS NO 156548-23-1 is a naturally occurring antimicrobial peptide (AMP) originally isolated from the hemolymph of the European firebug, *Pyrrhocoris apterus*. This compound is of significant interest for its potent activity against Gram-negative bacteria, including multi-drug resistant strains, by targeting the bacterial inner membrane. It serves as a valuable research tool and a promising lead compound for the development of novel anti-infective agents and preservatives. Key target industries include pharmaceutical R&D, biotechnology, and advanced materials science.

Application

• Antimicrobial Research & Development: As a model compound for studying the mechanism of action of proline-rich antimicrobial peptides and for designing novel antibiotics.
• Biotechnology Reagent: Used in microbiological assays to study bacterial membrane permeability and resistance mechanisms.
• Lead Compound Optimization: Serves as a structural template for the synthesis of analogs with enhanced stability, potency, or spectrum of activity.
• Biomaterial Coating: Potential application in creating antimicrobial surfaces for medical devices or implants to prevent biofilm formation.
• Preservative Development: Exploration of its use in formulations requiring protection against Gram-negative bacterial contamination.

Quality Control

Our Pyrrhocoricin is produced under stringent conditions to ensure batch-to-batch consistency and high biological activity. Each lot is characterized using advanced analytical techniques, including HPLC for purity assessment and Mass Spectrometry (MS) for identity confirmation. We provide comprehensive Certificates of Analysis (COA) detailing purity, peptide content, and endotoxin levels, supporting its use in critical research applications.

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). For long-term storage, consider lyophilized powder under inert atmosphere. Allow the vial to equilibrate to room temperature before opening to minimize moisture uptake.
