Recombinant Antibodies: The Antibody Technology That Solves Common Antibody Problems

Polyclonal and monoclonal antibodies have been the standard immunodetection reagent in different biomedical applications for more than forty years. Recently, shortcomings in both monoclonal and polyclonal antibodies are leading researchers to turn to antibodies manufactured by recombinant technologies.


A series of publications have illuminated the challenges of reproducible results using traditional commercial research-grade antibodies.

The reproducibility issues in the data emanate from a host of parameters including batch-to-batch variation and non-specific antibody binding. Polyclonal Abs originate from animal serum and each batch is prepared from a different animal or a different immunization. Monoclonal Abs, originating from a single B-cell clone have since been shown to express additional functional variable regions, leading to non-specific binding, decreased binding signal, and a decreased signal-to-noise ratio.

Recombinant antibodies have been developed to deliver true monospecific highly-sensitive immunodetection reagents to life science researchers worldwide.

What are Recombinant Antibodies?

Recombinant antibodies are a type of monoclonal antibodies that are generated in vitro from a synthetic gene without immunizing any animals or cultivating any hybridomas.


Abcepta’s recombinantly manufactured antibodies help you achieve:

  • Unrivaled batch-to-batch performance consistency
  • Confirmed specificity that will not drift over time
  • Scalability that ensures reliable, long-term supply of sequence-identical product
  • Antibody production without the need for animals

Recombinant Abs have several advantages as compared to monoclonals. The first is the increased reproducibility of the technology. The sequence of recombinant Ab gene is known and cloned, making them more reliable and more reproducible than monoclonals. The second advantage of recombinant antibodies over monoclonal antibodies is the time required to generate them. Hybridomas need multiple months to produce effective Abs, while recombinant Abs technology decreases the production time to just a few weeks. Finally, the generation and manufacturing of recombinant antibodies are animal-free technologies. The production process of recombinant Abs does not involve any animals.
