Human/Mouse/Rat RelA/NF kappa B p65 Antibody

Detection of Human and Mouse RelA/NF kappa B p65 by Western Blot. Western blot shows lysates of K562 human chronic myelogenous leukemia cell line, HeLa human cervical epithelial carcinoma cell line, and Neuro-2A mouse neuroblastoma cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human/Mouse/Rat RelA/NF kappa B p65 Monoclonal Antibody (Catalog # MAB5078) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for RelA/NF kappa B p65 at approximately 70 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Rat RelA/NF kappa B p65 by Western Blot. Western blot shows lysates of C6 rat glioma cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human/Mouse/Rat RelA/NF kappa B p65 Monoclonal Antibody (Catalog # MAB5078) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for RelA/NF kappa B p65 at approximately 65 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

RelA/NF kappa B p65 in K562 Human Cell Line. RelA/NF kappa B p65 was detected in immersion fixed K562 human chronic myelogenous leukemia cell line using Mouse Anti-Human/Mouse/Rat RelA/NF kappa B p65 Monoclonal Antibody (Catalog # MAB5078) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue).

Detection of RelA in HeLa Human Cell Line by Flow Cytometry. HeLa human cervical epithelial carcinoma cell line was stained with Mouse Anti-Human/Mouse/Rat RelA/NF kappa B p65 Monoclonal Antibody (Catalog # MAB5078, filled histogram) or isotype control antibody (Catalog # MAB0041, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0102B). To facilitate intracellular staining, cells were fixed with paraformadehyde and permeabilized with methanol.

Western Blot Shows Human RelA/NF kappa B p65 Specificity by Using Knockout Cell Line. Western blot shows lysates of HeLa human cervical epithelial carcinoma parental cell line and RelA/NF kappa B p65 knockout HeLa cell line (KO). PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human/Mouse/Rat RelA/NF kappa B p65 Monoclonal Antibody (Catalog # MAB5078) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for RelA/NF kappa B p65 at approximately 65 kDa (as indicated) in the parental HeLa cell line, but is not detectable in knockout HeLa cell line. GAPDH (Catalog # AF5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Human RelA/NFkB p65 by Western Blot Non-classical and intermediate monocytes express high levels of NF-kappa B (p65) and membrane-bound IL-1 alpha.a Western blot analysis of total p65 and GAPDH protein levels in the three monocyte subsets. b Quantification of Western blot data shown in (a): p65 protein level was normalized to GAPDH (loading control) and expressed as a fold change with respect to CL subset. The data represent the means ± SD; n = 3. c Relative levels of phosphorylated-p65 (p-p65), measured by flow cytometry. Each line represents one donor; n = 7. d IL-1 alpha secretion by the three monocyte subsets, measured by Luminex assay. The data represent the means ± SD; n = 3. e–f Relative expression levels of membrane-bound IL-1 alpha (e) and cytoplasmic IL-1 alpha (f), analyzed by flow cytometry. Each line represents one donor; n = 9. *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001.

Detection of Human RelA/NFkB p65 by Western Blot Tumor‐derived EVs activate the NF kappa B pathway. Primary CD14+ monocytes were incubated with TEVs isolated from conditioned PCI‐1 supernatants. (A) Lysates were generated at different timepoints of incubation and tested for I kappa B and phosphorylated P‐I kappa B. Tubulin was used as a loading control. (B) Primary monocytes were incubated with complete PCI‐1 supernatant (SN), in TEV‐depleted SN (depl.) or with isolated TEV for 120 min, nuclei were isolated and the translocation of NF kappa B‐p65 was tested with an immunoblot. Actin was used as a loading control, and the cytoplasmic fraction (p65/cyto) was used to confirm the specificity of the translocation. (C) Monocytes were incubated as in (B), and the binding capacity of NF kappa B p50 to the DNA was quantified with a NF kappa B binding assay kit.
