Rabbit monoclonal antibody production services

We are pleased to offer our powerful RabMAb® technology for creation of sensitive, specific custom rabbit monoclonal antibodies.

Our Custom Services team has record of successfully developing RabMAb primary antibodies against challenging targets such as splice variants, point mutations, species-specific orthologs, post-translational modifications, and small molecule compounds. More than 550 institutions and 150 pharma, diagnostics and biotech companies have benefited from our custom antibody development.

You can submit immunogens as recombinant proteins, synthetic peptides, small molecules, cDNA expression vectors, or over expressing cells. Alternatively, you can provide the spleen of an immunized rabbit to initiate the monoclonal phase of antibody development. Or better yet, you can simply provide the target information, and we will assist with antigen design and produce the immunogens.

RabMAb advantages

The rabbit immune system generates antibody diversity and optimizes affinity by mechanisms different from those of mice and other rodents. RabMAb technology produces reagents that combine the superior antigen recognition of a rabbit antibody with the specificity and consistency of a monoclonal. Two major advantages that set these apart from traditional mouse and rabbit antibodies are:

High affinity: On average, RabMAb primary antibodies have 10-100x higher affinity than mouse monoclonals, with KD values often in the picomolar (10-12 M) range and up to 10-14 M.

High specificity: Immunization of rabbits results in a highly diverse suite of B-lymphocytes and an abundance of splenocytes. The breadth of available cells means a greater chance of finding antibodies that distinguish between similar molecules and therefore improved specificity.
