Description

Myoglobin is a heme-containing, oxygen-binding protein primarily found in muscle tissue. Its unique iron-porphyrin complex makes it a critical molecule for studying oxygen transport, storage, and redox biochemistry. This high-purity protein is essential for research and development in life sciences, diagnostics, and biotechnology. Key industries that rely on consistent myoglobin supply include pharmaceutical research, clinical diagnostics, and food science.

Application

• Biochemical Research & Development: Used as a standard and model protein in studies of oxygen transport, protein structure-function relationships, and heme chemistry.
• Clinical Diagnostics: Serves as a key component and calibrator in immunoassay kits for the detection of muscle injury, including myocardial infarction (heart attack) and rhabdomyolysis.
• Food Science & Quality Control: Employed as an indicator of meat content and quality, and in studies related to meat color stability and oxidation.
• Pharmaceutical Development: Investigated for its potential therapeutic applications, including as an oxygen carrier in blood substitutes and in ischemia-reperfusion injury research.
• Educational & Reference Material: Supplied to academic and teaching institutions for laboratory experiments in biochemistry and physiology courses.
• Biotechnology: Utilized in the development of biosensors and bioanalytical devices due to its specific redox and ligand-binding properties.

Quality Control

Our myoglobin is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and reliability for critical applications. Each lot is characterized for identity, purity, and biological activity. We provide comprehensive Certificates of Analysis (COA) detailing specifications such as purity (by HPLC), absorbance ratios (A408/A280), and electrophoresis profile. Our quality commitment supports compliance with relevant guidelines for research and diagnostic use.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized powder at 2-8°C. Reconstituted solutions should be aliquoted and stored at -20°C or below to prevent degradation. The product is hygroscopic (moisture-sensitive); ensure the container is kept in a dry environment after opening.
