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

Eomesodermin homolog (UniProt: O95936; also known as T-box brain protein 2, T-brain-2, TBR-2) is encoded by the EOMES (also known as TBR2) gene (Gene ID: 8320) in human. T-box genes are a family of transcription factors have a highly conserved DNA binding domain named the T-domain. Tbr2 functions as a transcriptional activator that plays a crucial role during gastrulation, mesodermal specification, and limb patterning. It plays a role in brain development and is required for the specification and the proliferation of the intermediate progenitor cells and their progeny in the cerebral cortex. It is considered as the major intrinsic determinants of the intermediate neural progenitors. It is reported to be transiently expressed in cortical subventricular zone progenitor cells. Tbr2 is also involved in the differentiation of CD8+ T-cells during immune response regulating the expression of lytic effector genes. Its DNA-binding region (T-Box) is localized to amino acids 276-456. Conditional inactivation of Tbr2 during early brain development is known to cause microcephaly and severe behavior deficits. Four isoforms of Tbr2 have been described that are produced by alternative splicing. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
