Description

Phytochromobilin is a linear tetrapyrrole chromophore essential for the function of phytochrome photoreceptors in plants. This compound matters because it is the critical light-sensing component that enables plants to regulate growth, development, and flowering in response to red and far-red light. Industries and researchers involved in plant biology, agricultural biotechnology, and the development of light-regulated systems require high-purity Phytochromobilin for their work.

Application

• Plant Physiology & Photobiology Research: Fundamental studies on phytochrome function, signal transduction, and photomorphogenesis.
• Agricultural Biotechnology: Development of crops with optimized growth patterns, yield, and stress responses through manipulation of light-sensing pathways.
• Synthetic Biology: As a modular component for engineering novel light-regulated gene circuits and biosensors in various organisms.
• Biochemical Reagent: Used in in vitro assays to reconstitute active phytochrome apoproteins for functional studies.
• Phytochrome Biochemistry: Investigation of chromophore-protein interactions, photoconversion mechanisms, and spectral properties.

Quality Control

Our Phytochromobilin is produced and handled under strict quality protocols to ensure batch-to-batch consistency and high purity, suitable for sensitive research applications. Each lot is analyzed to confirm identity and purity, with comprehensive Certificates of Analysis (COA) provided. We adhere to relevant standards for high-purity biochemical reagents.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store desiccated at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation. Allow the sealed container to reach room temperature before opening to minimize moisture condensation.
