With a commitment to precision, reproducibility, and speed, we are your partner for efficient and reliable recombinant antibody solutions.

Why Choose Recombinant Antibody Production?

1. High Customization
   Recombinant antibody production allows for unparalleled flexibility in the design of antibodies. We can customize the antibody format, such as producing Fab fragments, full-length IgG, bispecific antibodies, or other antibody constructs, to meet your specific project needs. This approach also enables modification of the antibody’s sequence, isotype, and binding characteristics.
2. High Affinity and Specificity
   By leveraging advanced expression systems and protein engineering techniques, recombinant antibodies offer high affinity and specificity for their target antigen. These qualities make them ideal for applications requiring precise detection or therapeutic targeting, such as drug discovery, diagnostics, and personalized medicine.
3. Scalability and Reproducibility
   Recombinant antibody production ensures consistent, batch-to-batch reproducibility, eliminating the variability associated with traditional hybridoma or animal-based methods. Once the antibody gene is cloned, it can be produced at any scale, from small research quantities to large-scale manufacturing for clinical or industrial use.
4. Humanization and Engineering
   Recombinant antibodies can be engineered to improve therapeutic efficacy or minimize immunogenicity, such as by humanizing antibodies derived from non-human species. We also offer additional modifications like affinity maturation, isotype switching, Fc engineering, and antibody fragment production to meet your application’s requirements.
5. Rapid Production
   With recombinant technology, there is no need for the lengthy process of developing stable cell lines for antibody production. We can produce functional antibodies in a fraction of the time required for traditional methods, accelerating timelines for research, diagnostics, or therapeutic development.

Our Recombinant Antibody Production Workflow

1. Antibody Gene Design and Synthesis
   The process begins with designing the antibody sequence based on your specifications or derived from existing hybridomas, phage display libraries, or B cell screening. If you provide an antigen sequence or antibody variable regions, we can directly synthesize the gene encoding the desired antibody.
2. Cloning into Expression Vectors
   After designing or synthesizing the antibody gene, we clone it into high-efficiency expression vectors. These vectors are tailored to your choice of expression system, ensuring optimal expression levels for your project.
3. Recombinant Expression in Mammalian or Other Systems
   We offer a variety of expression platforms, including mammalian cells (e.g., HEK293, CHO cells) for high-quality, full-length antibody production. Depending on your application, we can also use bacterial, yeast, or insect cell systems for producing antibody fragments or other specialized constructs. Each system is chosen based on your project’s requirements for scalability, post-translational modifications, and production speed.
4. Antibody Purification
   After expression, we purify the recombinant antibodies using advanced techniques, such as protein A/G affinity chromatography, ion exchange, and size-exclusion chromatography. These methods ensure high-purity antibodies with optimal yield and functionality.
5. Quality Control and Characterization
   Every batch of recombinant antibodies undergoes rigorous quality control testing to ensure that they meet your specifications. We perform comprehensive characterization, including SDS-PAGE, Western blotting, ELISA, and binding affinity measurements, to verify antibody purity, integrity, and activity.
6. Delivery and Project Support
   Once your recombinant antibodies have been produced and purified, we deliver them in the format, concentration, and scale you need. We also provide ongoing technical support to ensure the antibodies perform as expected in your downstream applications.

Types of Recombinant Antibodies We Produce

• Monoclonal Antibodies
  Recombinant monoclonal antibodies are engineered to offer the highest specificity and affinity for a single epitope. They are ideal for therapeutic applications, research studies, and diagnostic tools where precise target detection is essential.
• Polyclonal Antibodies
  Recombinant polyclonal antibodies mimic the diverse response of the immune system, providing broader recognition across multiple epitopes. These are useful for applications that require detecting a range of antigenic sites, such as in assays or diagnostics.
• Bispecific Antibodies
  Bispecific antibodies are engineered to bind two different antigens simultaneously, making them ideal for complex therapeutic applications, such as targeted cancer therapies, where precise interaction with multiple targets is required.
• Antibody Fragments (Fab, scFv)
  We offer production of antibody fragments, such as Fab or single-chain variable fragments (scFv), which retain the antigen-binding specificity but are smaller in size. These fragments are ideal for applications where full-length antibodies are not required, such as imaging, neutralization assays, or drug conjugation.
• Humanized and Chimeric Antibodies
  For therapeutic use in humans, we can humanize non-human antibodies by replacing animal-derived sequences with human equivalents to reduce immunogenicity. We also produce chimeric antibodies that combine regions from different species to optimize therapeutic function.

Applications of Recombinant Antibodies

• Therapeutics and Drug Discovery
  Recombinant antibodies are critical in therapeutic development, including cancer immunotherapy, infectious disease treatment, and autoimmune disease management. Our customizable production services accelerate drug discovery pipelines by providing high-affinity antibodies for target validation and lead optimization.
• Diagnostics and Biomarker Detection
  High-affinity recombinant antibodies are essential for developing accurate diagnostic assays, such as ELISA, immunohistochemistry (IHC), flow cytometry, and lateral flow tests. With precise binding characteristics, recombinant antibodies enhance the sensitivity and specificity of diagnostic tools.
• Research and Functional Assays
  In academic and industrial research, recombinant antibodies are valuable tools for studying protein interactions, cellular processes, and disease mechanisms. They are commonly used in Western blotting, immunoprecipitation, and other molecular biology assays.
• Antibody Engineering and Custom Constructs
  Our recombinant technology allows for the production of custom antibody formats, including bispecific antibodies, Fc-fusion proteins, and other engineered constructs tailored to specific applications in therapeutics or research.
