Description

Cytochrome B6 CAS NO 9035-40-9 is a vital heme-containing protein complex integral to the photosynthetic electron transport chain in plants, algae, and cyanobacteria. Its primary function is to facilitate the transfer of electrons between photosystem II and photosystem I, a critical step in the conversion of light energy into chemical energy. This makes it an essential biochemical reagent for researchers in plant physiology, biochemistry, and molecular biology, as well as for developers in agricultural biotechnology and biofuel research.

Application

• Biochemical Research: A fundamental reagent for studying the structure, function, and kinetics of the cytochrome b6f complex in photosynthesis.
• Enzymology Studies: Used in assays to investigate electron transfer mechanisms, proton pumping, and the role of plastoquinone.
• Plant Physiology & Stress Response: Employed in research to understand photosynthetic efficiency under various environmental stresses such as drought, high light, or temperature extremes.
• Educational Purposes: Serves as a standard protein for laboratory teaching and demonstrations in advanced biology and biochemistry courses.
• Drug Discovery Screening: Potential target for the development of novel herbicides that inhibit the photosynthetic electron transport chain.
• Biofuel Research: Investigated in systems biology and synthetic biology approaches aimed at enhancing photosynthetic efficiency for biomass and biofuel production.

Quality Control

Our Cytochrome B6 is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and biological activity. Each lot undergoes comprehensive analytical testing, including purity assessment and functional activity assays. A Certificate of Analysis (COA) detailing specific results for purity, activity, and other critical parameters is provided with every shipment to support your research integrity and compliance needs.

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); ensure the container is sealed tightly after each use to minimize exposure to atmospheric moisture. For short-term use, keep at 2-8°C. Avoid repeated freeze-thaw cycles.
