Experimental details

Immunofluorescence analysis of Phospho-IKK alpha (Ser176, Ser180) was done on 70% confluent log phase HeLa cells. The cells were treated for 20 minutes with 50 ng/mL of TNF-Alpha and fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.25% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with Phospho-IKK alpha (Ser176, Ser180) Rabbit Polyclonal Antibody (Product # 44-714) at 1:250 dilution in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d is a merged image showing Nuclear localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.

Experimental details

Flow cytometry analysis of IKK alpha [pSpS176/180] was done on Jurkat cells treated with TNF alpha (50ng/mL, 10 minutes). Cells were fixed with 70% ethanol for 10 minutes, permeabilized with 0.25% Triton™ X-100 for 20 minutes, and blocked with 5% BSA for 30 minutes at room temperature. Cells were labeled with IKK alpha [pSpS176/180] Rabbit Polyclonal Antibody (44714, red histogram) or with rabbit isotype control (pink histogram) at 3-5 ug/million cells in 2.5% BSA. After incubation at room temperature for 2 hours, the cells were labeled with Alexa Fluor® 488 Goat Anti-Rabbit Secondary Antibody (A11008) at a dilution of 1:400 for 30 minutes at room temperature. The representative 10,000 cells were acquired and analyzed for each sample using an Attune® Acoustic Focusing Cytometer. The purple histogram represents unstained control cells and the green histogram represents no-primary-antibody control.

Experimental details

ChIP- qPCR analysis of IKK-alpha pSer176/pSer180 was performed with 10 µL of the Phospho IKK-alpha pSer176/pSer180 Rabbit polyclonal antibody (Product # 44-714) on sheared chromatin from 2 million HeLa cells treated with 50 ng/mL of TNF Alpha for one hour using the MAGnify™ Chromatin Immunoprecipitation System (Product # 49-2024). Normal Rabbit IgG was used as a negative IP control. The purified DNA from each ChIP sample was analyzed by StepOnePlus™ Real-Time PCR System (Product # 4376600) with primers for the promoter of active IL-8 gene, used as positive control target, and the SAT2, used as negative control target. Data is presented as fold enrichment of the antibody signal versus the negative control IgG using the comparative CT method.
