Why Choose Leading Biology for Antibody Production?


An antibody, also known as an immunoglobulin, is a Y-shaped protein produced mainly by plasma cells that is used by the immune system to neutralize pathogens such as bacteria and viruses. The production of antibodies is the main function of the humoral immune system. There is a small region known as the hypervariable region at the tip of the protein of an antibody, which is extremely variable. As the region allows millions of antibodies with slightly different tip structures, or antigen-binding sites, enormous diversity of antibody antigen-binding fragments called paratopes are generated by random recombination of a set of gene segments followed by random mutations in this area, and then create further diversity.


Antibodies used for lab research are often obtained from animals such as rabbits, sheep or mice with a specific antigen. Antibodies can be harvested in an antiserum, which is collected from an animal following exposure to an antigen. Because most antigens are complex structures with multiple epitopes, they result in the production of multiple antibodies in the animals.


Having been devoted decades of years to research, Leading Biology’s scientists have invented an advanced technology in our platform for Antibody Production & Purification, which has realized high pure antibody fractions with low endotoxin in preparation of the antibody by using the cell line.


Recombinant antibodies, produced by using recombinant antibody coding genes, are directly correlated to demand for therapeutic antibodies. They have been widely used in both medical and research applications for the advantages. The most commonly used form is the single chain variable fragment, which has shown the most promising traits exploitable in human medicine and research. In contrast to monoclonal antibodies produced by hybridoma technology, which may lose the capacity to produce the desired antibody over time or the antibody may undergo unwanted changes and thus affect its functionality. Recombinant antibodies produced in phage display maintain high standard of specificity and low immunogenicity.


The production of recombinant antibodies consists of the determination of the sequence of the desired product, gene synthesis and the construct generation. Once the construct is provided to us, expression constructs are produced, then they are transferred to the cell culture which will produce the desired recombinant antibody to be collected, purified and analyzed. It is important to achieve the assembly of a functional Fv fragment in Escherichia coli, which may have a great effect on its functionality of the antibody as it allows for further development and refinement of the recombinant antibodies in experiments.


Our strengths


Abundant Experience & Professional Engineers 


Our scientists with decades of expertise in generating custom antibodies ensure the processes for manufacturing the antibodies on your request.
