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.
DNA methyltransferases (Dnmts) methylate the 5-position of cytosine in the context of CpG dinucleotides. DNA methylation is crucial for normal embryonic development, genetic imprinting, and X-chromosome inactivation. Hypermethylation of DNA has been implicated in tumorigenesis through improper methylation of growth regulatory gene promoter regions. There exist three isoforms of Dnmts, Dnmt1, 2 and 3. Dnmt1 is believed to perform most of the maintenance and de novo methylation activities that occur in somatic cells of mammals. Studies have shown that Dnmt1 can establish repression of transcription complexes consisting of Dnmt1, histone deacetylase 2 (HDAC2), and DNA methyltransferase 1 associated protein (DMAP1). Therefore, in addition to DNA methylation maintenance, Dnmt1 is thought to directly target transcriptionally repressive chromatin to the genome during S-phase DNA replication.
