Description

Phytochrome CAS NO 11121-56-5 is a photoreversible pigment protein complex that plays a fundamental role in plant photomorphogenesis and light signaling. This compound is critical for researchers and industries focused on plant biology, agriculture, and biotechnology, as it regulates key developmental processes like seed germination, stem elongation, and flowering. It is an essential biochemical tool for academic institutions, agricultural research centers, and companies developing photoperiod-sensitive crops or controlled-environment agriculture solutions.

Application

• Plant Physiology & Photobiology Research: Fundamental studies on light perception, signal transduction, and photomorphogenesis in model plants and crops.
• Agricultural Biotechnology: Development of plant varieties with optimized growth characteristics, such as improved shade tolerance or controlled flowering times.
• Controlled-Environment Agriculture (CEA): Informing LED lighting spectra and photoperiod protocols in vertical farms and greenhouses to precisely manage plant growth and development.
• Seed Technology: Research into light-mediated seed dormancy and germination mechanisms to improve seed treatment and storage practices.
• Horticulture & Floriculture: Manipulation of flowering and plant architecture in ornamental plants and high-value crops through precise light quality control.
• Biochemical Reagent Production: Served as a high-purity standard or key component in assay kits for studying photoreceptor activity and interactions.

Quality Control

Our Phytochrome is produced and handled under stringent conditions to ensure biological activity and batch-to-batch consistency. Each lot undergoes rigorous analytical testing, including spectrophotometric analysis to confirm photoreversibility between its Pr (red-light-absorbing) and Pfr (far-red-light-absorbing) forms. Certificates of Analysis (COA) detailing purity, activity, and spectral characteristics are available upon request to support your research and development requirements.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store frozen at -20°C or below under an inert atmosphere. Avoid repeated freeze-thaw cycles. The product is easily oxidized; solutions should be prepared under inert conditions and used promptly.
