Protein Secondary Structure Analysis Service

Protein secondary structure analysis refers to the study of local spatial structures between continuous amino acid residues in proteins, mainly including α-helix, β-sheet, and others. Understanding protein secondary structures helps reveal their folding mechanisms, stability, function, and interactions with other biomolecules, providing important information for studying the biological functions and regulatory mechanisms of proteins. The principles of protein secondary structure analysis mainly rely on the specific responses of different structural elements (such as α-helix and β-sheet) to signals like light and magnetism. Common methods include circular dichroism (CD), Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), and X-ray crystallography.

MtoZ Biolabs offers a one-stop protein secondary structure analysis service using JASCO circular dichroism spectrometer, professionally determining the spatial configuration of proteins, including α-helix, β-sheet, and random coils, etc. Through the proportion and distribution information of protein sequence's secondary structure, the composition and changes of protein secondary structure are accurately revealed.

Analysis Workflow

1. Sample Preparation

Collect purified protein samples, remove impurities, adjust protein concentration and buffer to meet subsequent analysis requirements.

2. Spectrometer Calibration

Use a set of standard samples to calibrate the spectrometer, ensuring accurate measurement of the protein sample's CD spectra.

3. Spectra Collection

Place the protein sample in an optical cuvette and measure and collect CD spectra at different wavelengths (typically between 190-250 nm).

4. Data Processing and Analysis

Use professional software to analyze the measured CD spectra and convert them into proportions of protein secondary structures.

5. Results Interpretation

Interpret the protein's secondary structures based on the analysis results, assessing its folding degree, stability, and structural features.
