Description

Ste11 Transcription Factor CAS NO 145139-18-0 is a high-purity, biologically active protein critical for research in cellular signaling pathways. This product is essential for scientists studying the MAPK/ERK cascade, particularly in yeast model systems, to understand fundamental processes of cell growth, differentiation, and stress response. It is primarily utilized by researchers in academic institutions, pharmaceutical R&D, and biotechnology companies focused on molecular biology, genetics, and drug discovery.

Application

• Biochemical Research: Used as a key reagent in in vitro kinase assays to study phosphorylation events and signal transduction mechanisms.
• Yeast Genetics Studies: Essential for functional analysis of the pheromone response and filamentous growth pathways in Saccharomyces cerevisiae.
• Protein-Protein Interaction Analysis: Serves as a bait or prey protein in pull-down assays, co-immunoprecipitation, and yeast two-hybrid screens.
• Enzyme Kinetics: Employed to determine kinetic parameters and substrate specificity of MAPKKK activity.
• Educational Kits: Incorporated into advanced teaching kits for university-level courses in molecular and cellular biology.
• Drug Discovery Screening: Used as a target protein in high-throughput screening assays to identify potential inhibitors of the MAPK pathway.

Quality Control

Our Ste11 Transcription Factor is produced under stringent conditions to ensure batch-to-batch consistency and biological activity. Each lot undergoes rigorous quality testing, including purity assessment, activity assays, and confirmation of structural integrity. A comprehensive Certificate of Analysis (COA) detailing purity, specific activity, and storage buffer composition is provided with every shipment to support your research reproducibility.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C to -80°C in aliquots to avoid repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use. Avoid exposure to elevated temperatures.
