About Us – ProteoGenix, the Leading Antibody Production Company

Founded in 2003, ProteoGenix initially focused on developing diagnostic assays and biotherapeutics targeting discovered proteins. Recognizing the value of high-quality antibodies and proteins, ProteoGenix ventured into the biopharmaceutical domain, aiming to facilitate access to clinical settings, becoming a leading antibody production company.

ProteoGenix quickly gained recognition as a trusted Contract Research Organization (CRO) and a preferred partner in the biopharmaceutical industry. Its expertise in therapeutic antibodies and custom assay development significantly enhanced the success rate of its customized therapeutics, diagnostics, as well as research tools, thereby accelerating publications, reducing time-to-market and facilitating investigational stage of new drug application.

ProteoGenix is more than just an antibody production company. It also serves as a service integrator, guiding customers from early discovery to the clinic by anticipating future biologics requirements and designing tailor-made development strategies to proactively meet those needs. Its extensive portfolio of innovative solutions spans the following six complementary service areas:

          ✔ Antibody engineering (Antibody Humanization, Bi-specific antibodies, ADC, affinity maturation, antibody optimization)

          ✔ Bioprocess development (IP-free stable cell line development, fermentation, and bioreactor production optimization)

          ✔ Custom monoclonal & polyclonal antibody development (Hybridoma Cell Line Development, B cell Isolation, and Antibody Phage Display)

          ✔ Custom recombinant protein & antibody production services (E. coli, B. subtilis, Yeast, Insect cells, Mammalian cells)

          ✔ Gene synthesis

          ✔ Peptide synthesis

Our research and development labs constantly influence our processes with outstanding innovations like our proprietary XtenCHO™ cell line for industry-leading antibody expression in mammalian cells.

ProteoGenix also boasts an extensive catalog of over 7,000 products available in their user-friendly online shop. This comprehensive collection encompasses antibodies, proteins, ELISA kits, cell separation media, and nucleic acid purification kits, ensuring easy access to a wide range of research tools.

From Your Project Requirements to Your Custom Antibody: How the Process Works

When working with ProteoGenix on your custom antibody project, you can expect a step-by-step process that ensures high-performance results and tailored solutions for your specific needs.

          Project Discussion: At the start of the project, you will engage in detailed discussions with one of our antibody experts so we can understand your requirements, objectives, and project timeline. This collaborative approach allows for effective custom project design and ensures that our process is aligned with your goals.

          Antigen Preparation: Next, we will prepare a high-quality antigen that we will use to immunize animals or for use in antibody isolation (phage display) and purification. This involves the synthesis or production of the antigen based on the specifications discussed in the project discussion phase. Attention is given to ensuring the antigen’s quality, purity, and suitability for generating the desired antibody response.

          Animal Immunization: This step applies to polyclonal antibody development projects or monoclonal projects using single B cell isolation, hybridoma, or customs immune phage display library generation projects. Following antigen preparation, the selected animals will be immunized to stimulate the production of specific antibodies against the target antigen.

          Antibody Development: Once the animals have generated an immune response, blood samples will be collected, and the antibody-containing serum (polyclonal antibody production) or the B cell compartment (monoclonal antibody production) will be processed.

         ✔ Antibody Expression & Purification: In cases where recombinant antibody production is required, ProteoGenix will employ advanced expression systems to produce the antibodies in a controlled laboratory setting. This ensures consistent and scalable production of the desired antibodies. Following expression, purification methods will be utilized to obtain highly pure and functional antibodies.

Throughout the entire process, you can expect access to ProteoGenix’s experienced scientists, who will guide you from project design to delivery. Their expertise and attention to detail, along with rigorous quality assurance measures, will ensure the development process of customized antibodies meets your specifications and deliver reliable performance for your research or diagnostic applications.
