Regardless of whether an antibody is polyclonal, monoclonal or recombinant, it must always be properly validated The tissue culture supernatants of transfected host cell lines. Where polyclonal antibodies are purified directly from the serum of the immunized host, and monoclonals are purifiedįrom either hybridoma-derived tissue culture supernatant or ascites, recombinant antibodies are instead purified from Unlike traditional methods for antibody production, recombinant approaches avoid the need to use animals. Is assured in situations where an antibody will be used to support large, long-term studies, this can be an especially Moreover, since the recombinant antibody sequence is known, continuity of supply In vitro methods for producing antibodies are amenable to large-scale production, meaning antibody availability is RecombinantĪntibodies are highly consistent from lot to lot, thereby ensuring reproducible experimental results.
In contrast, hybridoma-based systems for producing monoclonal antibodies are subject to geneticĭrift and instability, increasing the potential for lot-to-lot variability or loss of antibody expression. Lines of bacterial, yeast, or insect origin are also suitable.īecause recombinant antibody production involves sequencing the antibody light and heavy chains, it is a highly controlledĪnd reliable process. Mammalian cell lines are most commonly used for recombinant antibody production, although cell Recombinant antibodies are monoclonal, but their production involves in vitro genetic manipulation.Īfter cloning the antibody genes into an expression vector, this is then transfected into an appropriate host cell lineįor antibody expression. Secreted by many different B cell clones and recognize multiple antigenic epitopes, monoclonals originate from a single BĬell clone and are specific for just one epitope. They are generated by immunizing an animal with an antigen to elicit an immune response. Traditional polyclonal and monoclonal antibodies are the product of normal B cell development and genetic recombination. These include superior lot-to-lot consistency, continuous supply, and animal-free manufacturing.Īs such, recombinant antibodies are seeing increased use for scientific research, especially as a means ofĪddressing the ongoing reproducibility crisis. Recombinant antibodies offer several key advantages compared to traditional antibodies. Available fields are: Gene name ( HGNC name or synonyms), Protein class, Chromosome, External identifier ( Ensembl gene, transcript or protein identifier, UniProt accession number, NCBI Entrez gene identifier), Subcellular location based on immunofluorescent staining in three different cell lines, Organ-, Tissue-, Cancer- and Cell line expression, Antibody validation results in four different assays ( IH=immunohistochemistry, IF=immunoflourescence, WB=Western blot, PA=Protein array), evidence scores and a filtration on Genes with antibodies only and Genes with knowledge-based annotated protein expression ( IH, IF).What is a Recombinant Antibody and Why is it Important?
