Immunofluorescent analysis of SY5Y cells using a Phospho-KLF4 pSer245 polyclonal antibody (Product # PA5-13081). SY5Y cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.2%, 30 min), then incubated with a Phospho-KLF4 pSer245 polyclonal antibody (Product # PA5-13081) (1:500, 2 hr at room temperature). Primary antibody detected by fluor-conjugated donkey anti-rabbit secondary antibody (green) was used (1:1000, 1hr). Cytoplasmic actin was counterstained with red dye conjugated phalloidin (5.25 uM, 25 min).

This antibody is predicted to react with mouse based on sequence homology.
Transcription factor; can act both as activator and as repressor. Binds the 5'-CACCC-3' core sequence. Binds to the promoter region of its own gene and can activate its own transcription. Regulates the expression of key transcription factors during embryonic development. Plays an important role in maintaining embryonic stem cells, and in preventing their differentiation. Required for establishing the barrier function of the skin and for postnatal maturation and maintenance of the ocular surface. Involved in the differentiation of epithelial cells and may also function in skeletal and kidney development. Contributes to the down-regulation of p53/TP53 transcription.
