Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting
Species predicted to react based on 100% sequence homology: Human, Rat, Monkey.
Specificity / Sensitivity
EOMES Antibody detects endogenous levels of total EOMES protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to amino acid sequences at the amino terminus of human EOMES. Antibodies are purified by protein A and peptide affinity chromatography.
The T-box family of transcription factors is named for their shared homology with the DNA binding domain of the mouse brachyury (T) gene product. Members of this family bind DNA and are capable of transcriptional activation. They also have evolutionarily conserved expression patterns and roles in embryonic development, primarily mesoderm development (1). EOMES, or Tbr2 (T-box brain 2), is a master regulator of mesoderm formation that is also essential for trophoblast formation, gastrulation, neurogenesis and the differentiation of certain T cell subsets. Embryos from EOMES knock-out mice die soon after implantation due to their inability to develop a trophoblast (2,3). Conditional neural knock out mice show defects in development of a specific population of neural progenators known as Intermediate Progenator Cells (IPCs) that give rise only to neurons (4,5). These cells are formed from the radial glia in the ventricular and sub-ventricular zones of the cortex. Expression of EOMES increases as cells develop from radial glia to IPCs and then decreases as IPCs progress to neurons. Recent evidence suggests that EOMES and IPCs may also play a role neurogenesis in the adult hippocampal SGZ (5). EOMES is also a key transcription factor for memory T cells and for full effector differentiation of CD8+ T cells (6). Expression of EOMES is induced in CD8+ T cells following viral infection and bacterial infection where sufficient IL-12 has been produced to elicit acute host cell response (7).
