Description

Hemoglobin Collingwood is a highly purified, specialized form of hemoglobin derived from bovine sources, identified by CAS No. 90142-28-2. This product is critical for applications requiring a consistent and reliable source of heme protein for research, diagnostics, and biochemical manufacturing. It is primarily utilized by biotechnology firms, diagnostic kit manufacturers, and academic research institutions engaged in hematology studies, oxygen carrier development, and as a standard in analytical chemistry.

Application

• As a primary standard or reference material in clinical and analytical laboratories for calibrating hemoglobin assays.
• Utilized in biomedical research for studying oxygen transport, blood substitutes, and heme protein biochemistry.
• Key component in the manufacturing of in-vitro diagnostic (IVD) reagents and test kits for blood analysis.
• Used in cell culture media supplements and specialized growth environments for certain cell lines.
• Employed as a catalyst or enzymatic mimic in certain chemical synthesis and oxidation reactions.
• Potential use in the development of biosensors and bio-analytical devices due to its redox properties.

Quality Control

Our Hemoglobin Collingwood is produced under strict quality management protocols. Each batch is tested to ensure high purity, consistent performance, and meets stringent specifications for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing identity, purity (by HPLC), methemoglobin content, and microbiological limits is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C. This material is light-sensitive and easily oxidized; prolonged exposure to air, light, or elevated temperatures should be avoided to maintain stability and potency. For long-term storage, consider keeping under an inert atmosphere.
