Animal-free antibodies are available from the sources listed below. Most companies offer a selection of catalog antibodies and custom antibody development, and generate antibody fragments and full immunoglobulin format. Note that this list is not comprehensive and that a number of the suppliers listed sell animal-derived antibodies in addition to animal-free recombinant antibodies.
Abcalis offers animal-free recombinant monoclonal antibodies and multiclonal antibodies produced in animal-serum free media.
Abcam produces a selection of antibodies using phage display recombinant antibody technology.
Absolute Antibody sequences and produces antibodies developed via phage display.
Adimab offers therapeutic antibody discovery and an antibody discovery platform transfer service.
AdipoGen Life Sciences generates and characterises animal-free recombinant monoclonal antibodies (RecMAbs™).
AvantGen provides a complete antibody discovery service using human antibody libraries.
Bio-Rad uses its Human Combinatorial Antibody Libraries (HuCAL) library to offer animal-free recombinant monoclonal antibodies. Catalog HuCAL antibodies can be found here by searching the HuCAL isotype.
Creative BioMart offers a limited catalog of animal-free recombinant antibodies.
The Geneva Antibody Facility develops animal-free recombinant antibodies at the University of Geneva and makes them available to the scientific community. Its ABCD (AntiBodies Chemically Defined) database is a curated depository of sequenced antibodies developed at the facility.
GenScript generates antibodies produced from customer-provided sequences.
The Human Antibody Core Facility at the Oklahoma Medical Research Foundation produces antibodies from human immune responses after vaccination.
IONTAS offers custom antibody discovery.
ProMab Biotechnologies develops animal-free recombinant antibodies from a human Fab library.
The Protein Capture Reagents Program includes a database listing antibodies developed by the Recombinant Antibody Network, a consortium of centers at the University of Chicago, University of California San Francisco, and the University of Toronto. Because both animal-derived antibodies and animal-free antibodies are listed in the database, the user much search for antibodies derived from phage-displayed fragment antigen-binding (Fab) libraries.
Specifica uses its own and custom libraries and a combined phage and yeast protocol to produce antibodies in the nanomolar and sub-nanomolar range.
YUMAB uses libraries containing naturally derived antibody sequences or custom libraries to develop fully human, therapeutic antibodies.
