Phosphorylation of NFKBIA at serine 32 represents a critical regulatory checkpoint in NF-κB signaling, marking IκBα for ubiquitination and subsequent proteasomal degradation. This phosphorylation event liberates NF-κB dimers to translocate to the nucleus and activate transcription of genes governing inflammation, immune responses, and cell survival. Detecting this specific phosphorylation state allows researchers to monitor pathway activation dynamics in response to inflammatory stimuli, stress signals, or therapeutic interventions.
This recombinant monoclonal antibody, generated from clone 2D6, offers the reproducibility and consistency that phospho-specific detection demands. Because the antibody sequence is defined and production occurs in a controlled recombinant system, researchers can expect uniform performance across experiments and over time, eliminating the lot-to-lot variability that can compromise longitudinal studies or multi-site collaborations.
Validation in western blot applications demonstrates reliable detection in A549 human lung adenocarcinoma cells, with clear discrimination between phosphatase inhibitor-treated and untreated lysates, confirming specificity for the phosphorylated epitope. The observed band at 39 kDa aligns precisely with the predicted molecular weight, indicating clean target recognition. For researchers investigating subcellular localization or pathway activation at the single-cell level, immunofluorescence validation in A549 cells provides confidence for imaging-based approaches, with the antibody performing effectively at dilutions suitable for standard microscopy workflows.
The flexibility to work across western blot, immunofluorescence, and ELISA platforms makes this antibody a versatile tool for signal transduction research, particularly studies examining NF-κB pathway regulation in inflammatory disease models, cancer biology, or immune cell activation contexts.
