Description

Interleukin 2 is a critical cytokine with the CAS registry number 268535-76-8, playing a pivotal role in regulating immune responses. Its primary commercial value lies in its application as a high-purity reference standard and active pharmaceutical ingredient (API) for research and therapeutic development. This product is essential for biotechnology firms, pharmaceutical manufacturers, and advanced research institutions focused on immunology, oncology, and cell therapy.

Application

• Pharmaceutical Development: Serves as a key active pharmaceutical ingredient (API) in the formulation of immunotherapies and biologics.
• Biomedical Research: Used as a critical reagent in immunological assays, T-cell proliferation studies, and signal transduction pathway analysis.
• Reference Standard: Employed as a high-purity calibrant in quality control (QC) and analytical method development for biopharmaceuticals.
• Cell Culture & Expansion: Facilitates the ex vivo expansion of T-cells and natural killer (NK) cells for adoptive cell transfer therapies.
• Diagnostic Kit Manufacturing: Incorporated into ELISA kits and other immunoassays for the detection of immune-related biomarkers.
• Pre-clinical & Clinical Studies: Utilized in animal models and clinical trials to investigate efficacy and mechanisms of novel immunomodulatory drugs.

Quality Control

Our Interleukin 2 is manufactured under strict quality management systems. Each batch is subjected to a comprehensive battery of analytical tests, including identity confirmation by mass spectrometry, purity assessment by high-performance liquid chromatography (HPLC), and rigorous testing for biological activity, endotoxins, and host cell proteins. A Certificate of Analysis (COA) detailing all specifications and results is provided with every shipment to ensure full traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized material at -20°C or below. Reconstituted solutions should be aliquoted and stored at -70°C to -80°C to prevent repeated freeze-thaw cycles. Due to its hygroscopic (moisture-sensitive) nature, the product must be handled in a dry environment.
