Specificity / Sensitivity

Phospho-C/EBPbeta (Ser105) Antibody (Rat Specific) detects endogenous levels of rat C/EBPbeta only when phosphorylated at serine 105. It does not cross-react with phosphorylated rat C/EBP family members alpha, delta, gamma, epsilon or zeta. It also does not recognize the p20 LIP rat C/EBPbeta isoform.

Phospho-C/EBPβ (Ser105)抗体(兔特异性)识别内源性的Ser105磷酸化的C/EBPβ。此抗体与其它磷酸化的C/EBP亚型α, δ, γ,ε或ζ没有交叉反应。它也不识别p20 LIP大鼠C/EBPβ亚型。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser105 of rat C/EBPbeta. Antibodies are purified by protein A and peptide affinity chromatography.


Western Blotting

Western Blotting

Western blot analysis of extracts from untreated or serum stimulated PC12 cells, using Phospho-C/EBPbeta (Ser105) Antibody (Rat Specific) (A, B) or C/EBPbeta Antibody #3082 (C, D). Nitrocellulose membranes B and D were treated with alkaline phosphatase (CIP) to show the phospho-specificity of Phospho-C/EBPbeta (Ser105) Antibody.

对PC12细胞抽提液(未处理或血清刺激),使用Phospho-C/EBPbeta (Ser105) Antibody (兔特异性) (A, B)或C/EBPbeta Antibody #3082 (C, D)进行Western blot分析。硝酸纤维素膜B和D经过碱性磷酸酶(CIP)处理以显示Phospho-C/EBPbeta (Ser105) Antibody的特异性。


CCAAT/enhancer-binding proteins (C/EBPs) are a family of transcription factors critical for cellular differentiation, terminal functions and inflammatory response (1). Six members of the family have been characterized (C/EBPα, -β, -γ, -δ, -ε and -ζ) and are distributed in a variety of tissues (1). There are two forms of C/EBPβ, the 38 kDa liver activating protein (LAP) and the 20 kDa liver inhibitory protein (LIP) which may be products of alternative translation. The 38 kDa LAP protein is a transcriptional activator while LIP may act as an inhibitor of C/EBPβ transcriptional activity (2). Phosphorylation of C/EBPβ at distinct sites stimulates its transcriptional activity (3-5). Phosphorylation at serine 105 of rat C/EBPβ, a unique site only present in the rat sequence, seems essential for rat C/EBPβ activation (6).

CCAAT/增强子结合蛋白(C/EBP)是一个转录因子家族,对细胞分化、终端功能和炎症反应十分关键(1)。目前已确定该家族的6个成员(C/EBPα, β, δ, γ, ε, ζ),它们分布在不同组织(1)。C/EBPβ有两种形式,38kDa的肝激活蛋白(LAP)和20kDa的肝抑制蛋白(LIP),它们可能是可变翻译的产物。38kDa LAP蛋白是转录激活因子,LIP是C/EBPβ的转录活性的抑制剂(2)。C/EBPβ不同位点的磷酸化刺激其转录活性(3-5)。大鼠C/EBPβ Ser105磷酸化是仅在大鼠序列中出现的一个独特位点,似乎对大鼠C/EBPβ的激活至关重要(6)。
