Description

Proteinase Inhibitor I (Plants) is a specific, naturally occurring compound that functions as a potent inhibitor of proteolytic enzymes in plant systems. This product is essential for researchers and manufacturers who require precise control over protein degradation pathways in plant-based samples and products. It is a critical reagent for plant molecular biology, biochemistry, and the development of plant-derived biopharmaceuticals, where maintaining protein integrity is paramount.

Application

• Inhibition of endogenous proteases during the extraction and purification of proteins from plant tissues.
• Stabilization of recombinant proteins expressed in plant-based expression systems (e.g., tobacco, algae).
• Component of extraction buffers for plant proteomics and metabolomics studies to prevent sample degradation.
• Use in plant cell culture to study programmed cell death and stress response mechanisms involving proteases.
• Research into plant-pathogen interactions, where protease inhibitors play a key defensive role.
• Formulation additive for plant-derived protein-based therapeutics and nutritional supplements to enhance stability.
