Description

Self-Incompatibility Glycoprotein, Nicotiana is a specialized plant glycoprotein isolated from the genus *Nicotiana*. This compound plays a critical role in the self-incompatibility (SI) mechanism, a genetic system that prevents inbreeding and promotes outcrossing in flowering plants. It is an essential research reagent for plant biologists, geneticists, and biochemists studying reproductive biology, pollen-pistil interactions, and signal transduction pathways. The material is supplied as a high-purity, lyophilized powder suitable for laboratory and research applications.

Application

• Plant Reproductive Biology Research: Fundamental studies on self-incompatibility mechanisms, pollen tube growth inhibition, and interspecific hybridization barriers.
• Biochemical Assay Development: Used as a standard or substrate in developing in vitro assays to study protein-carbohydrate interactions and signal transduction.
• Genetic and Molecular Studies: Investigating the S-locus genes, protein expression, and the molecular basis of speciation and plant evolution.
• Agricultural Biotechnology: Research aimed at manipulating self-incompatibility to control plant breeding and crop improvement programs.
• Comparative Biology: Studying the diversity and evolution of self-recognition systems across different plant families.
• Educational and Reference Standard: Serves as a high-quality reference material in academic and institutional teaching laboratories.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch of Self-Incompatibility Glycoprotein is characterized for identity, purity, and biological activity using advanced analytical techniques. Certificates of Analysis (COA) detailing specific test results for parameters such as protein content, glycosylation pattern, and functional activity are available upon request. We adhere to strict quality management protocols suitable for research-grade biochemicals.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. The product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to minimize moisture uptake. For long-term storage, keep desiccated at -80°C.
