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.

Anti-Centrin, clone 20H5 ZooMAb^®, Cat. No. ZMS1054, is a recombinant Mouse monoclonal antibody that specifically targets Centrin and is tested for use in Immunofluorescence, Immunohistochemistry (Paraffin), and Western Blotting.

Caltractin (UniProt: P05434; also known as 20 kDa calcium-binding protein, Centrin) is encoded by the VFL2 gene (Gene ID: 5725094) in Chlamydomonas reinhardtii (algae). Centrin is a highly conserved calmodulin-like calcium-binding phospho-protein that contain four EF hands and are associated with centrosome-related structures. In Chlamydomonas reinhardtii, centrin is shown to play an essential role in microtubule severing during flagellar excision during which time stellate fibers of the transition zone contract and displace the microtubule doublets of the axoneme inward. The resulting shear force and torsional load generated during inward displacement leads to microtubule severing immediately distal to the central cylinder of the transition zone. Centrin is also present is all eukaryotic cells and contain four helix-loop-helix motifs that all conform to the EF-hand consensus for Ca2+ binding. Two of these motifs exhibit high affinity for Ca2+ two display lower affinity. Stability of centrin is regulated by phosphorylation of serine residue in the C-terminal region by aurora kinase A, which also localizes with centrin at the centrosome. Their levels are shown to be the highest from prophase to metaphase stage followed by precipitous loss in the late stage of mitosis. In human breast cancers higher levels of aurora kinase A and phospho-centrin have been observed. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
