SOX2 is a master transcription factor essential for maintaining pluripotency in embryonic stem cells and regulating neural progenitor cell fate during development. Its expression serves as a critical marker in stem cell research, neuroscience, and cancer biology, where aberrant SOX2 activity has been implicated in tumor-initiating cell populations across multiple malignancies.
This recombinant monoclonal antibody, generated against a synthetic peptide derived from human SOX2, offers the consistency and reproducibility that demanding research applications require. Because the antibody sequence is defined and production occurs in a controlled recombinant system, you can expect reliable performance across experiments and between lots, eliminating a common source of variability in long-term studies.
Western blot validation demonstrates robust detection across human cell lines including U-251 glioblastoma and MCF-7 breast cancer cells, as well as mouse and rat brain tissue lysates, confirming cross-species reactivity that supports comparative studies. The observed band at approximately 40 kDa runs slightly higher than the 35 kDa predicted molecular weight, which is consistent with post-translational modifications commonly observed for transcription factors. For immunohistochemistry, validation in paraffin-embedded human brain tissue using heat-mediated antigen retrieval in citrate buffer confirms suitability for archival tissue analysis, with recommended dilutions ranging from 1:50 to 1:200.
Whether you are characterizing stem cell differentiation, investigating neural development, or examining SOX2 expression in tumor samples, this antibody provides the specificity and cross-species reactivity needed to advance your research in epigenetics, developmental biology, and signal transduction.
