STAT3 serves as a critical convergence point for numerous signaling cascades, translating extracellular signals into transcriptional responses that govern cell proliferation, survival, and immune function. Phosphorylation at serine 727 represents a key regulatory modification that modulates STAT3 transcriptional activity, working in concert with tyrosine 705 phosphorylation to fine-tune cellular responses. Dysregulated STAT3 signaling is implicated in inflammatory conditions and oncogenesis, making precise detection of its phosphorylation status essential for researchers investigating these pathways.
This recombinant monoclonal antibody, generated against a synthetic phosphopeptide encompassing the S727 site, offers the reproducibility that phospho-specific detection demands. Because the antibody sequence is defined and production occurs in a controlled recombinant system, you can expect consistent performance across experiments and projects, eliminating the lot-to-lot variability that can compromise longitudinal studies of signaling dynamics.
Validation across multiple platforms demonstrates genuine workflow flexibility. Western blot analysis in A549 cells, with and without EGF stimulation, confirms specific detection at the expected 98 kDa molecular weight, enabling straightforward assessment of STAT3 S727 phosphorylation in response to growth factor signaling. Immunohistochemistry testing in paraffin-embedded human breast cancer tissue opens avenues for examining STAT3 activation in clinical specimens and tumor microenvironment studies. Immunoprecipitation validation using Calyculin A-treated 293 cells, which stabilizes phosphorylation states, confirms the antibody's utility for enrichment strategies and downstream analysis of STAT3 complexes.
For researchers dissecting signal transduction mechanisms, particularly those examining how serine 727 phosphorylation contributes to STAT3-driven transcriptional programs in cancer biology or inflammatory signaling, this antibody provides a reliable tool for consistent, reproducible results.
