Description

Malformin A is a potent, naturally occurring cyclic pentapeptide mycotoxin produced by certain strains of *Aspergillus niger*. This compound is of significant interest in biochemical and pharmacological research due to its unique biological activities, including its ability to induce malformations in plant roots and exhibit cytotoxic effects. It serves as a critical reference standard and research tool for scientists in agrochemical, pharmaceutical, and toxicology sectors studying mycotoxin mechanisms, plant physiology, and bioactive natural products.

Application

• Phytotoxicity & Plant Physiology Research: Used as a standard to study plant growth regulators, root malformation, and the mechanisms of mycotoxin action in agricultural science.
• Biochemical & Pharmacological Studies: Employed in research investigating its cytotoxic, antimicrobial, and other bioactive properties for potential drug discovery pathways.
• Mycotoxin Analysis & Reference Standard: Serves as a high-purity analytical standard for the identification and quantification of Malformin A in food, feed, and environmental samples via HPLC or LC-MS.
• Cell Biology & Toxicology Research: Utilized in *in vitro* studies to examine its effects on cell morphology, proliferation, and apoptosis in various cell lines.
• Natural Product Chemistry: Acts as a model compound for the synthesis and structural analysis of complex cyclic peptides.

Quality Control

Our Malformin A is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity for research applications. Each lot undergoes comprehensive analysis, including identity confirmation by spectroscopic methods and purity assessment by chromatographic techniques. A detailed Certificate of Analysis (COA) containing lot-specific data is provided with every shipment to support your research and compliance needs.

Storage

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