* Product-specific protocol.
Specificity / Sensitivity
Phospho-Stat1 (Tyr701) (58D6) Rabbit mAb detects endogenous levels of Stat1 only when phosphorylated at tyrosine 701. The antibody detects phosphorylated tyrosine 701 of p91 Stat1 and also the p84 splice variant. It does not cross-react with the corresponding phospho-tyrosines of other Stat proteins.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr701 of human Stat1.

IF-IC
Confocal immunofluorescent analysis of HeLa cells, untreated (left) or IFNα-treated #9906 (right), using Phospho-Stat1 (Tyr701) (58D6) Rabbit mAb (green). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).
Chromatin IP
Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 HT-1080 cells treated with IFN-γ (50 ng/ml) for 30 minutes and either 5 μl of Phospho-Stat1 (Tyr701) (58D6) Rabbit mAb 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 human IRF-1 promoter primers, SimpleChIP® Human TAP1 Promoter Primers #5148, and SimpleChIP® Human α Satellite Repeat Primers #4486. 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.
Background
The Stat1 transcription factor is activated in response to a large number of ligands (1) and is essential for responsiveness to IFN-α and IFN-γ (2,3). Phosphorylation of Stat1 at Tyr701 induces Stat1 dimerization, nuclear translocation, and DNA binding (4). Stat1 protein exists as a pair of isoforms, Stat1α (91 kDa) and the splice variant Stat1β (84 kDa). In most cells, both isoforms are activated by IFN-α, but only Stat1α is activated by IFN-γ. The inappropriate activation of Stat1 occurs in many tumors (5). In addition to tyrosine phosphorylation, Stat1 is also phosphorylated at Ser727 through a p38 mitogen-activated protein kinase (MAPK)-dependent pathway in response to IFN-α and other cellular stresses (6). Serine phosphorylation may be required for the maximal induction of Stat1-mediated gene activation.

文献和实验：使用 Anti-phospho-Akt (Ser473) Rabbit mAb 对石蜡包埋的人乳腺癌组织进行免疫组织化学分析。（图 A）使用免疫组化试剂盒M&R HRP/DAB Detection IHC Kit，抗体 1:100 稀释；(图 B) 采用普通免疫组化试剂盒，抗体 1:25 稀释。 图 6 免疫组化实验检测 Erk1/2 表达 注：使用 Anti-Erk1/2 Mouse mAb与p44/42 MAPK （Erk1/2）Rabbit mAb 对正常小鼠心脏组织进行免疫
