Product Information

Product Usage Information

Application Dilution
Western Blotting 1:1000
Immunoprecipitation 1:100

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

EBF1 Antibody recognizes endogenous levels of total EBF1 protein. This antibody may detect nonspecific bands of unknown origin at 41 and 110 kDa. This antibody may cross-react with EBF2 and EBF3.

Species Reactivity:

Human

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly500 of human EBF1 protein. Antibodies are purified by peptide affinity chromatography.

Background

Early B-cell factor 1 (EBF1), also referred to as COE1, is a pioneering transcription factor that is crucial for defining B-cell lineage. In hematopoiesis, EBF1 promotes the expression of genes that specify B-cell lineage commitment, such as iFoxO1/i, iPAX5/i, and iIRF-4/i, while also repressing the expression of transcription factor genes that promote alternate lineages (1,2). EBF1 has also been reported to play a role in olfactory neuronal cell, adipocyte, and early osteoclast differentiation (3-6). Due to the crucial role of EBF1 in B-cell development, mutations in EBF1 can lead to the development of B-cell acute lymphoblastic leukemia (B-ALL) (7,8). EBF1 expression is also suppressed in some solid tumor cancers, including genomic loss in breast cancer and down-regulation in pancreatic ductal adenocarcinomas (9,10). Lower expression levels of EBF1 also correlate with lower survival rates in patients with cholangiocarcinoma and colorectal carcinoma (CRC), and induced overexpression of EBF1 in CRC cell lines induces cell cycle arrest and apoptosis in vivo and in vitro (11,12).

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 nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
