Recombinant Antibodies

OriGene's broad selection of monoclonal antibodies includes several recombinant antibodies, that are produced animal and animal-component-free using synthetic genes expressed in a defined in vitro cell line.

Though recombinant antibodies are standard in the pharmaceutical industry, these antibodies have not been as widely available for research. This is starting to change, however, due to the significant benefits recombinant antibodies offer over traditional hybridoma-produced monoclonal antibodies.

Currently, more than 1000 recombinant antibodies are available at OriGene!


  • Animal and animal-component- free
  • Low endotoxin levels
  • Monovalent, which means that these antibodies are highly specific and bind to a single antigen (unless described as bispecific)
  • Higher lot to lot reproducibility
  • Chimeric, bispecific, and other antibodies
  • In many cases well known clones, but available in a range of species and formats to best suit your assay needs

Product highlights within our recombinant antibody portfolio:


Biosimilars are biological compounds, almost identical to a reference biologic drug that have been approved by the U.S. Food and Drug Administration for medical treatment. Research-grade biosimilars are research tools for analysis of biological processes without the need to purchase expensive therapeutic-grade biologics.
