Stabilizing Enzymes for Continuous and High-Efficiency Biocatalysis

Enzyme immobilization involves selecting the best coupling chemistry and carrier material to suit the specific enzyme and its intended application. The primary goal is to minimize enzyme leaching and denaturation while maximizing the preservation of catalytic activity. Our process includes screening various immobilization methods against different carriers (e.g., acrylic beads, activated carbon, silica) to find the combination that provides the highest activity yield and thermal/pH stability. Whether you require mild adsorption for sensitive enzymes or robust covalent linkage for high-shear industrial reactors, our tailored approach ensures the creation of an optimized, reusable biocatalyst that significantly lowers operational costs.

FAQs about Enzyme Immobilization Services

Still have questions?

Contact Us

Which immobilization method is generally the most stable?

Covalent bonding and Cross-linked Enzyme Aggregates (CLEAs) generally offer the highest stability and resistance to leaching compared to physical adsorption, though the optimal method depends heavily on the specific enzyme's characteristics.

What is the difference between activity yield and stability?

Activity yield is the percentage of the original enzyme activity retained immediately after the immobilization process. Stability refers to the immobilized enzyme's ability to maintain that activity over time or across multiple reaction cycles (operational stability) or under harsh conditions (thermal/pH stability).

Can you immobilize enzymes sensitive to organic solvents?

Yes. We utilize strategies such as multipoint covalent attachment or encapsulation in biocompatible hydrogels, which offer a protective microenvironment to enhance the enzyme's tolerance to organic solvents or extreme temperatures.

What kind of characterization data is provided?

We provide comprehensive data, including immobilization efficiency, protein loading capacity, specific activity of the immobilized enzyme, activity yield, and full profiles of thermal, pH, and operational stability compared to the free enzyme.

How much does Metabolic Engineering services cost?

The cost of Metabolic Engineering services depends on the project scope, complexity of the target compound, the host organism chosen, and the required yield optimization. We provide customized quotes after a detailed discussion of your specific research objectives.

Do your engineered strains meet regulatory standards?

We adhere to high quality control standards in all strain construction and optimization processes. While we do not handle final regulatory approval, our detailed documentation and compliance with best laboratory practices ensure your engineered strains are prepared for necessary regulatory filings (e.g., GRAS, FDA).

What to look for when selecting the best gene editing service?

We provide various gene editing services such as CRISPR-sgRNA library generation, stable transformation cell line generation, gene knockout cell line generation, and gene point mutation cell line generation. Users are free to select the type of service that suits their research.

Does gene editing allow customisability?

Yes, we offer very customised gene editing solutions such as AAV vector capsid directed evolution, mRNA vector gene delivery, library creation, promoter evolution and screening, etc.

What is the process for keeping data private and confidential?

We adhere to the data privacy policy completely, and all customer data and experimental data are kept confidential.
