Quality Control

Our Ste4 Protein is manufactured under stringent conditions to ensure high purity, stability, and batch-to-batch consistency. Each lot undergoes comprehensive analytical testing, including SDS-PAGE, Western Blot, and functional activity assays. A detailed Certificate of Analysis (COA) documenting purity, concentration, endotoxin levels, and biological activity is provided with every shipment to support your research and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below in a non-frost-free freezer. Avoid repeated freeze-thaw cycles. This product is hygroscopic (moisture-sensitive); allow the vial to reach room temperature before opening to prevent condensation.
