Description

Rat IL-2 is a high-purity recombinant cytokine protein, specifically interleukin-2, derived from rat sources and identified by CAS NO 95568-40-4. This biologically active protein is essential for research into immune system regulation, T-cell proliferation, and inflammatory responses. It is a critical reagent for pharmaceutical R&D, academic research, and biotechnology applications focused on immunology and autoimmune disease studies.

Application

• Immunological Research: Used as a standard or stimulant in studies of T-cell activation, proliferation, and differentiation.
• Cell Culture: Essential component in media for the expansion and maintenance of primary T-cells and certain immune cell lines.
• Drug Discovery & Development: Serves as a target or tool compound in screening assays for novel immunomodulators and biologics.
• Biomarker Studies: Employed in the development and validation of ELISA, Western Blot, and other immunoassays to detect IL-2 levels.
• Autoimmune Disease Models: Applied in preclinical research to understand disease mechanisms in rat models of conditions like rheumatoid arthritis or transplant rejection.
• Vaccine Adjuvant Research: Investigated for its potential to enhance cellular immune responses in vaccine development platforms.

Quality Control

Our Rat IL-2 is produced under stringent conditions to ensure batch-to-batch consistency and biological activity. Each lot undergoes comprehensive analytical testing, including purity assessment by SDS-PAGE and HPLC, verification of identity, and determination of endotoxin levels. Certificates of Analysis (COA) detailing purity, potency, and specifications are provided to guarantee the material meets the high standards required for critical research applications.

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 -20°C to -80°C to avoid repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive); ensure containers are sealed properly after each use in a dry environment.
