Description

Staphyloferrin B CAS NO 127689-48-9 is a specialized siderophore, a high-affinity iron-chelating compound, originally identified in *Staphylococcus* species. This compound is critical for research focused on bacterial iron acquisition mechanisms, virulence, and the development of novel anti-infective strategies. It serves as an essential biochemical tool for microbiologists, pharmaceutical researchers, and academic institutions studying microbial metabolism and host-pathogen interactions.

Application

• Microbiological Research: Fundamental studies on bacterial iron transport systems and siderophore-mediated virulence in pathogens.
• Antimicrobial Development: Used as a reference compound or target in the discovery of novel antibiotics that disrupt iron scavenging pathways.
• Biochemical Assays: Acts as a specific chelator in assays designed to measure free iron concentrations or to study iron-dependent enzymatic processes.
• Host-Pathogen Interaction Studies: Investigation of how pathogens compete with host proteins for essential iron during infection.
• Analytical Standard: Serves as a high-purity reference standard for HPLC, LC-MS, or other analytical methods in research and quality control laboratories.
• Metallomics Research: Tool for understanding the role of specific siderophores in microbial metal homeostasis and environmental adaptation.

Quality Control

Every batch of Staphyloferrin B is produced and analyzed under strict quality protocols to ensure identity, purity, and consistency for critical research applications. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods. A comprehensive Certificate of Analysis (COA) detailing purity, assay results, and impurity profiles is provided with each shipment to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere, as the compound is easily oxidized. The container should be kept in a cool, dry, and well-ventilated area. Allow the product to reach room temperature in a desiccator before opening to prevent condensation.
