Detection of Human Phospho-RelA/NF kappa B p65 (S536) by Western Blot. Western blot shows lysates of HT‑29 human colon adenocarcinoma cell line and HeLa human cervical epithelial carcinoma cell line untreated (-) or treated (+) with 100 nM Calyculin A and 20 ng/mL Recombinant Human TNF‑ alpha (Catalog # 210-TA) for 10 minutes. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human Phospho-RelA/NF kappa B p65 (S536) Monoclonal Antibody (Catalog # MAB7226) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Phospho-RelA/ NF kappa B p65 (S536) at approximately 65 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.
Phospho-RelA/NFkB p65 (S536) in HT‑29 Human Cell Line. RelA/NF kappa B p65 phosphorylated at S536 was detected in immersion fixed HT‑29 human colon adenocarcinoma cell line untreated (lower panel) or treated with Calyculin A and Recombinant Human TNF‑ alpha (Catalog # 210-TA; upper panel) using Mouse Anti-Human Phospho-RelA/NF kappa B p65 (S536) Monoclonal Antibody (Catalog # MAB7226) at 2 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). Specific staining was localized to cytoplasm and cell surfaces. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: RelA/NFkB p65
RelA belongs to a family of transcription factors (NF kappa B (nuclear factor kappa from B cells) complex) that play a fundamental role in inflammatory and immune responses. The NF kappa B complex is composed of a heterodimer of a Rel family member (RelA, c-Rel, RelB) and either NF kappa B1 or NF kappa B2 subunits. RelA and NF kappa B1 are the most common heterodimeric pair. The NF kappa B complex is sequestered in the cytoplasm by inhibitory I kappa B proteins. Upon cellular activation, the ubiquitin-proteosome pathway degrades the I kappa B proteins allowing the NF kappa B complex to translocate to the nucleus and activate gene transcription.
