Study of abductin structure by Circular dichroism (CD) (CAT#: STEM-MB-0619-WXH)

Introduction

Abductin is a naturally occurring elastomeric protein found in the hinge ligament of bivalve mollusks. It is unique as it is the only natural elastomer with compressible elasticity, as compared to resilin, spider silk, and elastin. Its name was proposed from the fact that it functions as the abductor of the valves of bivalve mollusks.

Principle

Circular dichroism (CD) is a spectroscopy technique that measures the absorption difference between left and right circularly polarized light. By symmetry, this asymmetric absorption can only occur for asymmetric molecules, meaning chiral molecules.

Applications

Circular dichroism (CD) spectroscopy is a powerful technique that is sensitive to the chirality (handedness) of molecules. It can be used to study absolute stereochemistry, enantiomeric composition, racemization, enantiomeric differentiation, and molecular interactions and conformation.

Procedure

1. Sample preparation
2. Measurement by CD instrument
3. Data analysis

Materials

Circular dichroism (CD) spectrophotometer
