Description

Hemoglobin Willamette is a highly purified, naturally sourced heme protein derived from bovine blood. This product is critical for research and diagnostic applications requiring a stable and consistent source of hemoglobin for calibration and assay development. It serves as an essential biochemical reagent for laboratories in the life sciences, clinical diagnostics, and pharmaceutical development sectors. Its defined properties make it suitable for use as a standard or a key component in oxygen-binding studies and hematology controls.

Application

• Diagnostic Reagent Manufacturing: Used as a primary standard in the calibration of hemoglobinometers and clinical analyzers.
• Biochemical Research: Serves as a model protein for studying oxygen transport, ligand binding kinetics, and porphyrin chemistry.
• Quality Control in Pharmaceuticals: Employed in the development and validation of assays for blood-based therapeutics and oxygen carriers.
• Hematology Reference Materials: A key component in the formulation of quality control materials and calibrators for complete blood count (CBC) tests.
• Educational Kits: Supplied for university and training laboratory experiments in biochemistry and physiology.
• Bio-sensor Development: Utilized in the research and prototyping of optical and electrochemical sensors for oxygen detection.
