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.

Target description

Tumor suppressor ARF (UniProt: Q8N726; also known as Alternative reading frame, ARF, Cyclin-dependent kinase inhibitor 2A, p14ARF) is encoded by the CDKN2A (also known as CDKN2, MLM) gene (Gene ID: 1029) in human. p14ARF serves as a tumor suppressor and is a key regulator of cellular proliferation. It is shown to be frequently inactivated in human cancers. It binds to MDM2 and blocks its nucleocytoplasmic shuttling by sequestering it in the nucleolus. This inhibits the oncogenic action of MDM2 by blocking MDM2-induced degradation of p53 and enhances p53-dependent transactivation and apoptosis. Also induces G2 arrest and apoptosis by preventing the activation of cyclin B1/CDC2 complexes. It can form a ternary complex with p120(E4F) and p53 to enhance p14ARF-induced G2 cell cycle arrest in a p53-dependent manner. p14ARF also binds to E2F1 and MYC and blocks their transcriptional activator activity without affecting MYC transcriptional repression. Human p14ARF is shown to promote the proteasomal degradation of Melanoma antigen-A11 (MAGE-A11) independent of HDM2 E3 ubiquitin ligase or lysine ubiquitination. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
