Recombinant Collagen Structure Characterization Service

Recombinant collagen structure characterization is a structural evaluation designed for collagen products expressed through genetic engineering, aiming to systematically analyze the formation of triple-helix structures, thermal stability, aggregation state, and structural similarity to native collagen. This service integrates multiple high-resolution analytical techniques, including circular dichroism (CD) spectroscopy, differential scanning calorimetry (DSC), dynamic light scattering (DLS), and size-exclusion chromatography coupled with multi-angle light scattering (SEC-MALS), to reveal the advanced structural features of recombinant collagen from multiple dimensions.

Recombinant collagen structure characterization service is widely applied in fields such as tissue engineering, biomedical materials, regenerative medicine, and functional skincare. It provides critical data support for functional validation, process optimization, quality control, and regulatory submission, ensuring structural safety and application effectiveness of collagen-based products.

Services at MtoZ Biolabs

Based on advanced instrumentation platforms including CD spectroscopy, DSC, SEC-MALS, and DLS, the recombinant collagen structure characterization service launched by MtoZ Biolabs enables systematic analysis of key structural features such as triple-helix formation, thermal stability, molecular aggregation state, and particle size distribution of recombinant collagen. This service provides multidimensional data outputs, including denaturation temperature, secondary structure composition, aggregation profiles, and molecular size, helping clients evaluate the structural integrity and functional compatibility of recombinant collagen, and supporting product development and quality control.

Analysis Workflow

1. Sample Receipt and Preprocessing

After the client submits liquid, lyophilized, or gel-form collagen samples, MtoZ Biolabs performs concentration measurement and buffer exchange based on experimental requirements to ensure sample suitability for structural analysis.

2. Secondary Structure Evaluation

Circular dichroism (CD) spectroscopy is used to assess the secondary structure composition of collagen, determine the formation of the triple-helix structure, and calculate the proportions of α-helix, β-sheet, and other structural elements.

3. Thermal Stability and Aggregation Analysis

Differential scanning calorimetry (DSC) is used to measure the thermal denaturation temperature (Tm), while SEC-MALS and DLS are employed to evaluate collagen aggregation behavior, molecular weight distribution, and particle size, providing a comprehensive profile of higher-order structure.

4. Data Analysis and Report Delivery

The acquired data are processed through curve fitting and comparative analysis, yielding key indicators such as Tm values, structural composition, and particle size distribution. A detailed structural interpretation and quality evaluation report is provided to support product development and regulatory submission.

Sample Submission Suggestions

1. Sample Type

Liquid, lyophilized powder, or gel forms of recombinant collagen are accepted. Purified samples are recommended, and components that may interfere with structural analysis—such as high salt, strong reducing agents, or surfactants—should be avoided.

2. Storage and Transportation

Samples should be stored at low temperatures (–20°C or –80°C). During transportation, cold chain shipping with dry ice or ice packs is recommended. Repeated freeze-thaw cycles should be avoided to maintain structural integrity.

3. Additional Information

Please provide basic sample details, including expression system, buffer composition, and any additives present, to help optimize the analytical workflow and ensure accurate data interpretation.
