Structural analysis of Antimicrobial Peptides by Circular dichroism (CD) (CAT#: STEM-MB-0638-WXH)

Introduction

Antimicrobial peptides (AMPs) are a class of small peptides that widely exist in nature and they are an important part of the innate immune system of different organisms. AMPs have a wide range of inhibitory effects against bacteria, fungi, parasites and viruses.

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
