Description générale

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.

Description de la cible

WW domain-containing transcription regulator protein 1 (UniProt: Q9GZV5; also known as Transcriptional coactivator with PDZ-binding motif, TAZ) is encoded by the WWTR1 (also known as TAZ) gene (Gene ID: 25937) in human. TAZ is an oncogenic transcriptional activator that acts as a downstream regulatory target in the Hippo signaling pathway that plays a pivotal role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis. It is shown to be highly expressed in kidney, heart, placenta, lung and in the thyroid tissue. It concentrates along specific portions of the plasma membrane and accumulates in punctate nuclear bodies. It binds to transcription factors via its WW domain. The ability of TAZ to regulate gene transcription is very tightly regulated through the phosphorylation-dependent binding of 14-3-3 protein. Its phosphorylation by LATS2 results in creation of 14-3-3 binding sites, retention in the cytoplasm, and functional inactivation. Phosphorylation also results in the inhibition of transcriptional coactivation through Tyrosine 3-Monooxygenase/Tryptophan 5-Monooxygenase Activation Protein Zeta (YWHAZ). Its nuclear retention is achieved by Mediator of RNA polymerase II transcription subunit 15 (MED15). TAZ is shown to be involved in non-small-cell lung cancer and its higher expression levels are observed in breast cancer and in breast cancer stem cells. It also regulates embryonic stem-cell self-renewal and promotes cell proliferation and epithelial-mesenchymal transition. Loss of TAZ leads to inhibition of TGF signalling and differentiation into a neuroectoderm lineage. In the absence of TAZ, Smad2/3-4 complexes fail to accumulate in the nucleus and activate transcription. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Forme physique

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.


300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Stockage et stabilité

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
