Here is a list of over 180 custom antibody suppliers with a brief categorization of the kind of services that they provide. Definitions of descriptors are as follows:

1. peptides - indicates that a company will synthesize peptide haptens. Visit the Peptide Resource Page if you are interested in custom peptide synthesis.  It is important to note that as a hapten a peptide may not achieve the same effect as a native protein. Such factors that limit the utility of a peptide in this application are the 3-dimensional structure of the peptide, which may differ from the whole protein, and the antigenicity of the peptide.  Various prediction tools exist to calculate peptide antigenicity.

2. recombinant proteins - indicates that a company will express recombinant protein immunogens

3. DNA - indicates the company can perform cDNA immunizations to generate antibodies
