Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to amino acid sequence surrounding Ser270 of human ETO. Antibodies are purified by protein A and peptide affinity chromatography.
Background
ETO belongs to a family of evolutionarily conserved nuclear factors. Although it has no DNA binding domains it is reported to act as a transcriptional corepressor (1). It is best characterized as the fusion partner of AML1 in acute myeloid leukemia with the t(8;21) translocation which gives rise to the AML-ETO fusion protein (2). AML1 is a transcription factor that is involved in the differentiation of all hematopoietic lineages. The fusion protein lacks the activation domain of AML1 and behaves as a dominant negative AML1, repressing AML1 target genes. AML-ETO also causes activation of other genes through a mechanism that involves Bcl-2 and enhanced expression of p21 waf1/cip1 (3,4). The AML-ETO fusion protein is thought to cause the expansion of a hematopoietic stem cell population that has limited lineage commitment and genomic instability (5). Recent evidence derived from chromatin immunoprecipitation (ChIP) experiments has demonstrated that ETO may play a role in the regulation of Notch target genes, and AML-ETO has been shown to disrupt repression of Notch target genes (6). Therefore, both AML and Notch target genes are deregulated by AML-ETO. Epigenetic silencing of the microRNA-223 gene has also been attributed to activities of AML-ETO, contributing to the differentiation block in t(8;21) leukemia (7).

Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
