Description

Self Incompatibility Associated Protein S3, Solanum Chacoense CAS NO 135374-33-3 is a specialized plant protein involved in the self-incompatibility (SI) mechanism of *Solanum chacoense*, a wild potato species. This protein plays a critical role in preventing self-fertilization by mediating the recognition and rejection of self-pollen, thereby promoting genetic diversity. It is an essential research reagent for plant biologists, geneticists, and agricultural scientists studying reproductive biology, plant breeding systems, and the molecular basis of SI. The availability of this characterized protein supports advanced research in developing breeding strategies and understanding cellular recognition pathways in plants.

Application

• Fundamental Plant Biology Research: Investigating the molecular mechanisms of self-incompatibility (SI) signaling cascades and pollen-pistil interactions.
• Genetic and Protein Functional Studies: Used in assays to characterize protein function, ligand binding, and interaction partners within the SI system.
• Agricultural Science & Crop Improvement: Aiding research aimed at manipulating compatibility systems for hybrid seed production and breeding programs in Solanaceae crops.
• Biochemical Reagent: Serving as a standard or antigen in the development of immunoassays, western blotting, and other protein detection methods.
• Educational & Reference Material: Used in advanced university laboratories for teaching concepts in plant reproduction and protein biochemistry.

Quality Control

Our Self Incompatibility Associated Protein S3 is produced and handled under controlled conditions to ensure batch-to-batch consistency and high biological activity for research applications. Each lot undergoes rigorous quality testing, including purity assessment and functional validation where applicable. Certificates of Analysis (COA) detailing specific test results are available upon request to support your research and regulatory documentation 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). Allow the vial to equilibrate to room temperature in a dry environment before opening to minimize moisture uptake. For extended storage, consider under an inert atmosphere.
