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.

Nicotinate-nucleotide pyrophosphorylase [carboxylating] (UniProt: Q15274; also known as EC:2.4.2.19, Quinolinate phosphoribosyltransferase [decarboxylating], QAPRTase, QPRTase) is encoded by the QPRT gene (Gene ID: 23475) in human. QPRTase is a hexameric enzyme formed by three homodimers. It is involved in de novo synthesis of NAD using quinolinic acid (QA) as a precursor that is produced via the degradation of tryptophan in kynurenine pathway. In mammals QA is shown to be an excitotoxic compound that can lead to neurodegeneration via over activation of NMDA receptors. The only known known pathway for QA elimination is via decarboxylation and conjugation with phosphoribosylpyrophosphate to form nicotinamide mononucleotide (NaMN) that is catalyzed by QPRTase. In brain, QPRTase is shown to be preferentially localized in glial cells and in neurons of the cerebral ventricles. Its levels in liver are shown to be several-folds higher than in brain. QPRTase has three QA binding sites (aa 138-139; 160-161; and 248-250) and the region consisting of amino acids 8-12 is important for hexamer formation. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
