Recombinant Antibody Production ServiCE

Recombinant antibodies are antibody fragments generated in vitro through the use of synthetic genes. In contrast to the traditional antibodies produced by hybridoma technology, recombinant antibodies offer numerous advantages, including the preservation of high standards of specificity and low levels of immunogenicity.

Our team possesses extensive expertise in the field of recombinant antibody production. We proudly provide a comprehensive solution that encompasses a wide range of antibody fragment formats.


Our services span from initial hybridoma sequencing and gene synthesis to the intricate stages of transient/stable cell line expression, meticulous purification and QC, and thorough characterization. This one-stop solution can be tailored to your specific needs, ensuring a seamless and efficient process from start to finish.
