Description

Hemoglobin Poissy is a high-purity, well-characterized form of hemoglobin, a vital oxygen-transporting metalloprotein found in red blood cells. This product is essential for research and development in life sciences, providing a reliable standard for biochemical studies and diagnostic applications. It is particularly valuable for researchers and manufacturers in the pharmaceutical, biotechnology, and clinical diagnostics sectors who require consistent, high-quality protein materials for their work.

Application

• Biochemical Research Standard: Used as a reference material in spectroscopic studies, oxygen-binding kinetics, and protein interaction assays.
• Diagnostic Reagent Development: Serves as a key component in the formulation of controls and calibrators for hematology analyzers and blood gas instruments.
• Pharmaceutical Research: Employed in studies exploring oxygen therapeutics, blood substitutes, and drug delivery systems.
• Enzyme & Cell Culture Studies: Acts as a source of heme or an oxygen carrier in specialized cell culture media and enzymatic reaction systems.
• Educational & Quality Control: Provides a defined protein source for academic laboratory instruction and internal quality control processes in diagnostic manufacturing.
