Description

Globulins, Sheep Gamma CAS NO 68476-36-8 is a high-purity immunoglobulin fraction isolated from ovine (sheep) serum, primarily composed of IgG antibodies. This product is essential for research, diagnostic, and biopharmaceutical applications requiring a well-characterized animal-derived antibody source. It is particularly valuable for scientists and manufacturers in immunology, assay development, and as a critical reagent in control preparations.

Application

• Immunological Research & Assay Development: Used as a standard or control in ELISA, Western blotting, and other immunoassays to study antibody-antigen interactions.
• Diagnostic Kit Manufacturing: Serves as a key component in the production of diagnostic test kits, including those for autoimmune diseases and infectious agents.
• Cell Culture & Microbiology: Employed as a supplement in cell culture media or as a blocking agent to reduce non-specific binding in various biological assays.
• Pharmaceutical Reference Standard: Acts as a quality control standard in the production and validation of therapeutic antibodies and other biological products.
• Comparative Immunology Studies: Provides a reference point for cross-species immunological comparisons and evolutionary studies of the immune system.
• Antibody Purification & Conjugation: Used as a starting material or model protein for developing and optimizing antibody purification, fragmentation, and labeling techniques.

Quality Control

Our Globulins, Sheep Gamma is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity, consistent activity, and low endotoxin levels. Certificates of Analysis (COA) detailing specifications for purity (by electrophoresis), protein content, and biological activity are available upon request to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C for long-term stability. This product is hygroscopic (moisture-sensitive); ensure the container is sealed properly after each use to prevent moisture absorption. For extended storage, consider aliquoting and freezing at -20°C or below.
