Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation, ChIP=Chromatin IP,

Specificity / Sensitivity

Stat5 Antibody detects endogenous levels of total Stat5α and β protein.

Stat5 抗体能检测内源总体水平的 Stat5α 和 Stat5β蛋白。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to an amino-terminal region within Stat5. Antibodies were purified by protein A and peptide affinity chromatography.

此多克隆抗体是通过合成对应人源性Stat5 N-末端区域的肽段免疫动物而获得。 抗体是通过protein A和多肽亲和层析法纯化。

Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 BaF3 cells starved of IL-3 for 6 hours followed by induction with IL-3 for 45 minutes, and either 20 μl of Stat5 Antibody or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by Real-Time PCR using SimpleChIP® Mouse CIS Intron 1 Primers #5131, mouse SOCS3 promoter primers, and SimpleChIP® Mouse RPL30 Intron 2 Primers #7015. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.染色质免疫共沉淀。BaF3细胞培养至4 x 106, 并经IL-3饥饿处理6小时后经IL-3诱导45Min,然后用SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003进行免疫沉淀实验,本实验中用20 μl Stat5 抗体 或2 μl Normal Rabbit IgG #2729 。用using SimpleChIP® Mouse CIS Intron 1 Primers #5131对富集的DNA做real-time PCR,所用引物为mouse SOCS-3 promoter primers和SimpleChIP® Mouse RPL30 Intron 2 Primers #7015。每个样本中沉淀的DNA量定义为相对信号与输入的总染色质相比的数值。


Stat5 is activated in response to a wide variety of ligands including IL-2, GM-CSF, growth hormone and prolactin. Phosphorylation at Tyr694 is obligatory for Stat5 activation (1,2). This phosphorylation is mediated by Src upon erythropoietin stimulation (3). Stat5 is constitutively active in some leukemic cell types (4). Phosphorylated Stat5 is found in some endothelial cells treated with IL-3, which suggests its involvement in angiogenesis and cell motility (5). Stat5a and Stat5b are independently regulated and activated in various cell types. For instance, interferon treatment predominantly activates Stat5a in U-937 cells and Stat5b in HeLa cells (6).

Stat5的激活是通过一系列的配体的结合而完成,包括 IL-2, GM-CSF,生长激素和泌乳刺激素。磷酸化Tyr694位点对 Stat5的活性是必须的(1,2)。此位点的磷酸化是在红细胞生成素的作用下由Src介导而完成(3)。 Stat5在某些白血病类型的细胞中有组成性的活性(4)。用IL-3处理的内皮细胞中有磷酸化的Stat5,这就表明它参与了血管再生和细胞的运动(5)。在不同细胞类型中 Stat5a 和 Stat5b 是被独立调控和激活的。例如,干扰素处理后在U-937细胞中Stat5a的活性较强但在HeLa细胞中Stat5b的活性较强(6)。
