Flow Cytometry (Intracellular) - Anti-STAT6 (phospho Y641) antibody [EPR22599-52] - ChIP Grade (AB235591)

Intracellular flow cytometric analysis of 4% paraformaldehyde fixed 90% methanol permeabilized Daudi (Human Burkitt's lymphoma lymphoblast) was serum starved for 24h, then treated with 100ng/ml IL-4 for 15min (Red) / Untreated control (Green) cells labelling STAT6 (phospho Y641) with ab235591 at 1/500 (Red) compared with a Rabbit monoclonal IgG (ab172730) / Black isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). A Goat anti rabbit IgG (Alexa Fluor^® 488, ab150077) at 1/2000 dilution was used as the secondary antibody.

Immunoprecipitation - Anti-STAT6 (phospho Y641) antibody [EPR22599-52] - ChIP Grade (AB235591)

STAT6 (phospho Y641) was immunoprecipitated from 0.35 mg Daudi (Human Burkitt's lymphoma lymphoblast) cells serum starved for 24h, then treated with 100ng/ml IL-4 for 15min whole cell lysate, with ab235591 at 1/30 dilution (2ug in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab235591 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366) was used at 1/5000 dilution.

• ChIP

Unknown

ChIP - Anti-STAT6 (phospho Y641) antibody [EPR22599-52] - ChIP Grade (AB235591)

Chromatin was prepared from Daudi cells starved for 24h, then treated with hIL-4(100ng/ml, 15min) according to the Abcam Dual-X-ChIP protocol. Cells were fixed with 1.5 mM EGS for 30mins and then formaldehyde for 10min.
The ChIP was performed with 25 μg of chromatin, 5 μg of ab235591 (red), or 5 μg of rabbit normal IgG ab172730 (gray) and 20 μl of Protein A/G sepharose beads. The immunoprecipitated DNA was quantified by real time PCR (Taqman approach for active and inactive loci, Sybr green approach for heterochromatic loci).
Primers and probes are commercial primers from Cell Signaling Technology (Cat. No. : #56554)
