Description

Hevein is a small, cysteine-rich lectin protein originally isolated from the rubber tree (*Hevea brasiliensis*). This compound is of significant interest in biochemical and pharmaceutical research due to its potent chitin-binding activity and role in plant defense mechanisms. It serves as a valuable reference standard and research tool for scientists in the fields of plant biology, immunology, and drug discovery, particularly in studies related to antifungal activity, protein-carbohydrate interactions, and allergic responses.

Application

• Biochemical Research: Used as a reference standard and probe in studies of lectin-carbohydrate interactions, particularly with chitin and chitin oligosaccharides.
• Pharmaceutical Development: Investigated for its potential antifungal properties and as a model for developing novel antimicrobial agents.
• Allergen Studies: Serves as a key antigen in research on latex allergy, helping to understand immune responses and develop diagnostic tools.
• Plant Defense Mechanism Research: Utilized to study the role of pathogenesis-related (PR) proteins in plant innate immunity against fungal pathogens.
• Structural Biology: Employed in protein folding and stability studies due to its compact, disulfide-stabilized structure.

Quality Control

Our Hevein is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability for research applications. Each lot is characterized using advanced analytical techniques, including mass spectrometry and chromatography, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing purity, biological activity (where applicable), and analytical results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake.
