Description

Recombinant Staphylokinase CAS NO 9040-61-3 is a highly purified, genetically engineered fibrinolytic enzyme derived from *Staphylococcus aureus*. This product is critical for applications requiring precise and efficient clot dissolution, offering superior consistency and activity compared to native forms. It is an essential reagent for pharmaceutical R&D, diagnostic kit manufacturing, and biochemical research focused on thrombosis and hemostasis.

Application

• Thrombolytic Agent Research & Development: A key active ingredient in the study and formulation of novel clot-dissolving pharmaceuticals.
• Diagnostic Reagent Production: Used in the manufacture of in-vitro diagnostic kits for assessing fibrinolytic activity and coagulation disorders.
• Biochemical Research: Employed as a model enzyme in studies of protease mechanisms, protein-protein interactions, and fibrinolysis pathways.
• Reference Standard: Serves as a high-purity standard for quality control and assay calibration in pharmaceutical and diagnostic laboratories.
• Enzyme Engineering Studies: Utilized as a starting point for mutagenesis and protein engineering to develop variants with altered properties.

Quality Control

Our Recombinant Staphylokinase is manufactured under controlled conditions to ensure the highest standards of purity and biological activity. Each batch undergoes rigorous analytical testing, including SDS-PAGE, HPLC for purity, and specific activity assays. A comprehensive Certificate of Analysis (COA) documenting identity, purity, potency, and endotoxin levels is provided with every shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store desiccated at -20°C or below. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a dry environment before opening to prevent condensation and moisture uptake.
