Description

Cytochrome C551 From Pseudomonas is a highly purified heme protein isolated from *Pseudomonas* species, serving as a critical electron transfer component in bacterial respiratory chains. This product is essential for researchers and developers requiring a well-characterized, high-purity redox protein for biochemical studies and diagnostic applications. It is primarily utilized in life science research, enzymatic assay development, and as a component in biosensor platforms.

Application

• Biochemical Research: Used as a model protein for studying electron transfer mechanisms, protein folding, and heme-protein interactions.
• Enzyme Assay Development: Serves as a cofactor or electron donor/acceptor in the development of novel enzymatic assays and diagnostic kits.
• Biosensor Fabrication: Incorporated into electrode surfaces for the construction of amperometric biosensors and biofuel cells.
• Comparative Biochemistry: Employed in comparative studies with mitochondrial cytochromes c to understand evolutionary divergence in electron transport systems.
• Pharmaceutical Intermediates: Potential use as a starting material or reference standard in the development of novel therapeutic agents.
