Recombinant Antibodies and Proteins

Defined, reproducible and safe!

Recombinant proteins are produced in biotechnological processes using genetically modified organisms or transfected cell cultures, such as E. coli, various types of yeast or cell lines of insect or mammalian cells. This type of production offers the advantage of a defined genetic background with a short production time and simple culture conditions. The genetic modification of the proteins and the application of fusion tags is easily possible. Recombinant proteins are an important tool for diagnostics and medical development, as well as for biochemical analysis methods and biomedical research applications.
Recombinant antibodies with their high biological definability and safety, which are already standard for therapeutic applications, are also increasingly finding their way into research laboratories. In addition to reproducibility, they offer the advantage of new experimental possibilities through antibody engineering.

Our quality suppliers from all over the world together with our scientific and logistical expertise make BIOZOL your reliable source for recombinant antibodies and proteins.

Absolute Antibody

Engineered Antibodies for All

Absolute Antibody follows the vision that all antibody users should be able to use recombinant antibodies, which are absolutely defined by their amino acid sequence. Rather than creating entirely new antibodies (or antibody-like molecules), Absolute Antibody manufactures existing antibodies (often from hybridomas) in a superior way, improving their usefulness by engineering.

Absolute Antibody offers you a unique reagents catalog of engineered recombinant antibodies and Fc Fusion proteins. Since its founding, the company has produced more than 180 different antibody formats, as well as developed a reagents catalog of more than 13,000 engineered recombinant antibodies, and manufactured more than 21,000 different antibodies, making 865 grams of protein in total.

Aviva Systems Biology

Engineered Recombinant Antibodies

Aviva Systems Biology has been providing quality antibodies, ELISA Kits, recombinant proteins, and custom services for nearly 20 years. With over 500,000 catalog products and expertise in antibody and protein production, scientists rely on Aviva to obtain the reagents they need for their research. Aviva Systems Biology now also offers recombinant antibodies.

Aviva Systems Biology now offers recombinant antibodies

Recombinant antibodies can be engineered to have high specificity and selectivity for their target antigen. Through the use of recombinant DNA technology, specific antibody sequences can be identified, cloned, and expressed, ensuring precise targeting of the desired epitope. This specificity reduces the chances of cross-reactivity with unrelated antigens, leading to more accurate and reliable results. Recombinant antibodies can be produced in a controlled and standardized manner, ensuring batch-to-batch consistency. The benefits of specificity, reproducibility, and engineered properties make recombinant antibodies valuable tools in many research and application areas, including diagnostics, therapeutics, and molecular imaging.

Bio X Cell

Recombinant Monoclonal Antibodies for in vivo Applications

For over 20 years, scientists have trusted Bio X Cell as their go-to source for in vivo functional grade antibodies. Bio X Cell offers 300 high-quality, pure in vivo monoclonal antibodies covering a broad spectrum of your research needs.

Bio X Cell RecombiMAb™ monoclonal antibodies are recombinant antibodies with the exact same antigen binding variable domains as the traditional antibodies that they are derived from. The epitope to which the RecombiMAb™ antibody binds is identical to that of the matching traditionally produced clone. This is accomplished by sequencing and cloning the antibody-coding genes into high-yield expression vectors which are then expressed in mammalian cells to generate the recombinant antibody.
