Western blot analysis of extracts from various cell lines using Stat3α (D1A5) XP ® Rabbit mAb (top), Stat3 (124H6) Mouse mAb #9139 (middle), or β-Actin (D6A8) Rabbit mAb #8457 (lower).
Immunohistochemical analysis of paraffin-embedded cell pellets, HeLa (left) or PC-3 (right), using Stat3α (D1A5) XP ® Rabbit mAb.
Immunohistochemical analysis of paraffin-embedded human colon carcinoma using Stat3α (D1A5) XP ® Rabbit mAb in the presence of control peptide (left) or antigen-specific peptide (right).
Confocal immunofluorescent analysis of HeLa cells, serum-starved (left) or treated with Human Interferon-α1 (hIFN-α1) #8927 (100 ng/mL, 30 min; right) using Stat3α (D1A5) XP ® Rabbit mAb (green) and β-Actin (8H10D10) Mouse mAb #3700 (red).
Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 10 6 Hep G2 cells starved overnight and treated with Human Interleukin-6 (hIL-6) #8904 (100 ng/ml, 30 min), and either 5 μl of Stat3α (D1A5) XP ® 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 c-Fos Promoter Primers #4663, 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.
