Study of hemoglobin by Linear dichroism (LD) (CAT#: STEM-ST-0112-WXH)

Introduction

Hemoglobin (Hb) is the protein contained in red blood cells that is responsible for delivery of oxygen to the tissues. To ensure adequate tissue oxygenation, a sufficient hemoglobin level must be maintained.

Principle

Linear dichroism (LD) or diattenuation is the difference between absorption of light polarized parallel and polarized perpendicular to an orientation axis. It is the property of a material whose transmittance depends on the orientation of linearly polarized light incident upon it. LD measurements are based on the interaction between matter and light and thus are a form of electromagnetic spectroscopy.

Applications

Study the functionality and structure of molecules.

Materials

• Polarizer
• Absorbance spectrometer
