Anti-STAT1 antibody [EPR23049-111] - BSA and Azide free

• ICC/IF

Unknown

Immunocytochemistry/ Immunofluorescence - Anti-STAT1 antibody [EPR23049-111] - BSA and Azide free (AB263866)

Immunofluorescent analysis of 4% Paraformaldehyde-fixed, 0.1% TritonX-100 permeabilized HeLa (human cervix adenocarcinoma epithelial cell) cells labelling STAT1 with ab239360 at 1/50 dilution, followed by ab150077 AlexaFluor^®488 Goat anti-Rabbit secondary antibody at 1\1000 dilution (Green). Confocal image showing the signal translocate to nuclear in HeLa cells treated with IFN-γ (10ng/ml) for 30 mins. ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor^® 594) was used to counterstain tubulin at 1/200 dilution (Red). The Nuclear counterstain was DAPI (Blue).

Secondary antibody only control : Secondary antibody is ab150077 AlexaFluor^®488 Goat anti-Rabbit secondary at 1/1000 dilution.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab239360).

• ChIP

Unknown

ChIP - Anti-STAT1 antibody [EPR23049-111] - BSA and Azide free (AB263866)

Chromatin was prepared from HT-1080 cells treated with IFN-γ (50ng/ml 30min) 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 ab239360 (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. : #5148)

• Flow Cyt (Intra)

Unknown

Flow Cytometry (Intracellular) - Anti-STAT1 antibody [EPR23049-111] - BSA and Azide free (AB263866)

Intracellular flow cytometric analysis of 4% paraformaldehyde-fixed, 90% methanol permeabilized RAW264.7 (mouse Abelson murine leukemia virus-induced tumor macrophage) cells labelling STAT1 with ab239360 at 1/600 (Red) compared with a Rabbit monoclonal IgG (ab172730)isotype control (black)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 was used as the secondary antibody.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab239360).

• IP

Unknown

Immunoprecipitation - Anti-STAT1 antibody [EPR23049-111] - BSA and Azide free (AB263866)

STAT1 was immunoprecipitated from 0.35mg RAW264.7 (mouse Abelson murine leukemia virus-induced tumor macrophage) whole cell lysate with ab239360 at 1/30 dilution (2ug in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab239360 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366) was used at 1/5000 dilution.
