ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Proliferating cell nuclear antigen (UniProt: P12004; alsoknown as PCNA) is encoded by the PCN gene (Gene ID: 5111) in human. PCNA is a homotrimeric nuclear protein thatserves as an auxiliary protein of DNA polymerase delta and is involved in thecontrol of eukaryotic DNA replication by increasing the polymerase′sprocessability during elongation of the leading strand. It Induces a robuststimulatory effect on the 3′-5′ exonuclease and 3′-phosphodiesterase, but notapurinic-apyrimidinic (AP) endonuclease, APEX2 activities. It is reported tocolocalize with CREBBP, EP300 and POLD1 to sites of DNA damage. It acts as aloading platform to recruit DDR proteins that allow completion of DNAreplication after DNA damage and promote post-replication repair. PCNA canundergo phosphorylation on tyrosine 211 by EGFR that stabilizeschromatin-associated PCNA. Following DNA damage, it can undergomonoubiquitination to stimulate direct bypass of DNA lesions by specialized DNApolymerases or polyubiquitination to promote recombination-dependent DNAsynthesis across DNA lesions by template switching mechanisms. Mutation in PCN gene are known to causeAtaxia-telangiectasia-like disorder 2 (ATLD2) that is characterized bydevelopmental delay, ataxia, hearing loss, and short stature. This ZooMAb^® recombinant monoclonal antibody, generated by our proprietary technology,offers significantly enhanced specificity, affinity, reproducibility, andstability over conventional monoclonals.
