Recombinant rabbit monoclonal antibodies are produced using in vitro expression systems. The expression systems are developed by cloning in the specific antibody DNA sequences from immunoreactive rabbits. Then, individual clones are screened to select the best candidates for production. The advantages of using recombinant rabbit monoclonal antibodies include: better specificity and sensitivity, lot-to-lot consistency, animal origin-free formulations, and broader immunoreactivity to diverse targets due to larger rabbit immune repertoire.
In humans, the multiple tumor suppressor 1 locus (MTS1) encodes two unrelated genes, p16INK4a and p19ARF. Although both act as cell proliferation inhibitors, their mechanisms of action are different. p19ARF works as part of a p53-dependent pathway to counter uncontrolled proliferation and oncogenic signals. Mice lacking the p19ARF gene rapidly develop a broad spectrum of tumors. This result indicates that p19ARF is an important tumor suppressor. In addition, p19ARF helps prevent transforming signals from various onocoproteins via the p53 regulatory loop. These studies and others display the importance of p19ARF in cell cycle control and tumor suppression.
