C/EBPα Antibody

2295:

Immunofluorescence , Western Blotting

C/EBPα Antibody detects endogenous levels of total C/EBPα protein.

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the sequence of humanC/EBPα. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western blot analysis of extracts from THP1 and NIH/3T3-L1 cells using C/EBPα Antibody.

IF-IC

CCAAT/enhancer-binding proteins (C/EBPs) are a family of transcription factors that are critical for cellular differentiation, terminal function, and inflammatory response (1). Six members of the family have been characterized (C/EBPα, β, δ, γ, ε, and ζ) and are distributed in a variety of tissues (1). Translation from alternative start codons results in two isoforms of C/EBPα (p42 and p30), which are both strong transcriptional activators (2). It has been reported that insulin and insulin-like growth factor-I stimulate the dephosphorylation of C/EBPα, which may play a key role in insulin-induced repression of GLUT4 transcription (3). Phosphorylation of C/EBPα at Thr222, Thr226, and Ser230 by GSK-3 seems to be required for adipogenesis (4).
