Description

Ferrichrome Iron-Free From Ustilago is a high-purity, iron-free derivative of the natural siderophore ferrichrome, isolated from the fungus *Ustilago*. This compound is of significant interest as a critical biochemical tool for studying iron transport and chelation mechanisms without the interference of iron ions. It is essential for researchers and manufacturers in life sciences and biotechnology who require precise molecular probes for metallobiology, microbiology, and pharmaceutical development. The product is supplied as a high-quality standard to ensure reliable and reproducible experimental results.

Application

• Biochemical Research: Used as a key reference standard and chelating agent in studies of microbial iron acquisition, siderophore function, and metal homeostasis.
• Pharmaceutical Development: Serves as a precursor or intermediate in the research and development of novel antimicrobial agents and iron-chelating therapies.
• Microbiology & Cell Culture: Employed in defined media formulations to create iron-limited conditions for studying bacterial and fungal growth and virulence.
• Analytical Standards: Utilized as a certified reference material (CRM) for the calibration of analytical instruments like HPLC and mass spectrometry in metabolite analysis.
• Enzyme Studies: Acts as a specific inhibitor or substrate in enzymatic assays related to iron metabolism and siderophore biosynthesis pathways.
• Plant Science Research: Applied in studies investigating plant-microbe interactions and the role of siderophores in rhizosphere ecology.
