CD-Based Peptide Secondary Structure Analysis Service refers to a comprehensive service that utilizes circular dichroism (CD) spectroscopy to assess the secondary structure, estimate structural composition, and evaluate the thermal stability of peptide samples in solution. This service is primarily used in scientific research, drug development, and biopharmaceutical characterization to rapidly determine whether a peptide adopts typical conformations such as α-helix, β-sheet, or random coil, and to monitor structural stability under varying environmental conditions.

The three-dimensional conformation of peptide molecules directly determines their bioactivity and function. Secondary structures such as α-helices and β-sheets play central roles in various biological processes, including signal transduction, target recognition, and enzyme inhibition. Circular dichroism (CD) spectroscopy is an analytical technique based on the differential absorption of left- and right-handed circularly polarized light by optically active peptide molecules. Chiral groups within peptides—such as peptide bonds, aromatic amino acid residues, and disulfide bridges—interact with circularly polarized light, generating elliptically polarized light as a result of this differential absorption. By detecting the characteristics of this elliptically polarized light, researchers can derive valuable information about the peptide's secondary structure.
Leveraging a dedicated CD spectroscopy platform, MtoZ Biolabs offers CD-Based Peptide Secondary Structure Analysis Service to support detailed investigations of peptide conformations, structural dynamics, and thermal stability. This service provides critical data for drug design, functional prediction, and biopharmaceutical development.
Analysis Workflow
The general workflow of CD-Based Peptide Secondary Structure Analysis Service is as follows:
1. Sample Preparation
Samples are pretreated according to their specific characteristics.
2. CD Scanning
High-sensitivity circular dichroism spectrometers are used to scan peptide samples and acquire their CD spectra.
3. Data Analysis
CD data are analyzed using specialized software to identify secondary structure features such as α-helices, β-sheets, and random coils, and to calculate their respective percentages.
4. Report Delivery
A detailed report is provided, including secondary structure spectra, quantitative analysis of structural composition, and interpretation of structural changes.
