Description

Cryptogein CAS NO 115742-70-6 is a highly specific proteinaceous elicitor derived from the plant pathogenic oomycete *Phytophthora cryptogea*. This compound is of significant interest in plant biology and agricultural research due to its ability to trigger a hypersensitive response and systemic acquired resistance in certain plant species. It serves as a critical tool for researchers studying plant-pathogen interactions, signal transduction pathways, and plant defense mechanisms. Industries involved in agricultural biotechnology, crop protection research, and advanced plant science utilize this purified protein for experimental and developmental purposes.

Application

• Plant Defense Mechanism Research: Used as a model elicitor to study hypersensitive response (HR) and systemic acquired resistance (SAR) in plants.
• Signal Transduction Studies: Employed in biochemical assays to investigate the early signaling events in plant cells following pathogen recognition.
• Agricultural Biotechnology: Serves as a reference compound in the development and screening of new plant protection agents or resistant crop varieties.
• Plant Physiology: Utilized to examine the downstream effects of defense activation on plant metabolism, ion fluxes, and reactive oxygen species production.
• Academic and Institutional Research: A key reagent for universities and research institutes focused on molecular plant-microbe interactions.
• Phytopathology: Applied in studies to understand the virulence factors of oomycetes and the basis of plant susceptibility or resistance.

Quality Control

Our Cryptogein is produced and handled under controlled conditions to ensure batch-to-batch consistency and biological activity. Each lot undergoes rigorous quality testing, including purity assessment via electrophoresis (SDS-PAGE) and HPLC, confirmation of protein identity, and functional activity bioassays. Certificates of Analysis (COA) detailing the specifications and test results are available upon request to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized material at -20°C or below. Reconstituted solutions should be aliquoted and stored at -80°C to prevent repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive); ensure containers are sealed tightly in a dry environment after each use.
