    NCCIT cells were fixed with 1% paraformaldehyde (PFA) for 10 minutes at 37°C, permeabilized with 0.5% Triton X-100 at room temperature for 10 minutes and blocked for 30 minutes at room temperature with 5% fetal bovine serum (FBS). Then the cells were stained with anti-human SOX2 (clone 14A6A34) Alexa Fluor® 488 (green) overnight, followed by Phalloidin Alexa Fluor® 594 (red) for 20 minutes at 4°C. The nuclei were counterstained with DAPI (blue). The image was captured with 40X objective.

SOX2 is the most studied member of SRY-related box transcription factor family. It binds to target genes through its highly conserved HMG box domain. Inactivation of the SOX2 gene causes lethality during embryonic development. SOX2 knockdown in embryonic stem cells results in their differentiation. Co-expression of SOX with OCT4, MYC, and KLF4 is sufficient to reprogram somatic cells to induced pluripotent stem cells (iPSCs), which exert similar characteristics as natural pluripotent stem cells. These findings indicate that SOX2 is crucial for the self-renewal and pluripotency of embryonic stem cells. In addition, over-expression of SOX2 has been found in various types of malignant cancer. Knockdown of SOX2 results in cell cycle arrest by downregulating cyclin D1 and inhibition of tumor cell proliferation, suggesting that SOX2 is involved in activating genes associated with tumor progression.

Recommended Usage

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per million cells in 100 µl volume. For immunocytochemistry, a concentration range of 1.0 - 5.0 μg/ml is recommended. It is recommended that the reagent be titrated for optimal performance for each application.

* Alexa Fluor® 488 has a maximum emission of 519 nm when it is excited at 488 nm.
