Reactivity Key:  H=Human  Mk=Monkey
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.

Protocols

Specificity / Sensitivity

AML1 antibody detects endogenous levels of total AML1 protein and the AML1/ETO fusion protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to amino acids near the amino terminus of human AML1. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from Jurkat and Kasumi-1 cells, using AML1 Antibody.

Flow Cytometry

Flow Cytometry

Flow cytometric analysis of Jurkat cells, using AML1 Antibody (blue) compared to a nonspecific negative control antibody (red).

IF-IC

IF-IC

Confocal immunofluorescent image of Jurkat cells labeled with AML1 Antibody (green). Mitochondria have been labeled with MitoTracker Red CMXRos.


Background

AML1 (also known as Runx1, CBFA2, and PEBP2αB) is a member of the core binding factor (CBF) family of transcription factors (1,2). It is required for normal development of all hematopoietic lineages (3-5). AML1 forms a heterodimeric DNA binding complex with its partner protein CBFβ and regulates the expression of cellular genes by binding to promoter and enhancer elements. AML1 is commonly translocated in hematopoietic cancers: chromosomal translocations include t(8;21) AML1-ETO, t(12;21) TEL-AML, and t(8;21) AML-M2 (6). Phosphorylation of AML1 on several potential serine and threonine sites, including Ser249, is thought to occur in an Erk-dependent manner (7,8).
