SOX2 (SRY-RELATED HMG-BOX GENE 2), the basic helix-loop-helix transcription factor, is indispensable for maintaining embryonic stem (ES) cell pluripotency. The gene expresses in self-renewing progenitor cells and acts to inhibit neuronal differentiation. SOX2, along with other transcription factors Oct3/4, klf4, and c-Myc are used to generate induced pluripotent stem cells from mouse fibroblasts by retrovirus mediated introduction. It is expressed throughout the human brain, including the developing hypothalamus, as well as the Rathke pouch, the developing anterior pituitary and the eye. It is necessary for the normal development of the hypothalamo-pituitary and reproductive axes in mice. Mutation of the SOX2 gene in progenitor cells leads to cerebral malformation, severe eye defects, and hypothalamo-pituitary abnormalities.

FAQs for SOX2 Antibody (NB110-37235). (Showing 1 - 3 of 3 FAQs).

  1. We are looking for the following markers to use to stain cells derived from both human and mouse embryonic and induced pluripotent stem cells: undifferentiated cells, neurons, oligodendrocytes, and astrocytes.
    • For ES markers some popular targets are OCT4 (NB100-2379), KLF4 (NBP2-17070) and SOX2 (NB110-37235). PEA15 is expressed in Astrocytes and this might be one of interest for you (NBP1-61390). OCT4 is one that can also be expressed in Oligodendrocytes.
  2. As part of an Endometriosis-related project in horses, I would like to ask some information with regard to this. I would like to know about its tested or predicted reactivity with horse.
    • This antibody has not yet been tested with horse. This means that use of this antibody with horse would not be covered by our guarantee; however, you would be eligible for our Innovator's Reward Program. For an indication of the likely cross-reactivity (how well the antibody is likely to perform with horse), I have run UniProt Blast sequence comparison of the immunogen sequence versus horse proteins. For SOX2 Antibody NB110-37235, the exact immunogen is available to me in our internal notes. The UniProt Blast of this gave a 100% match with the (again, unfortunately unreviewed) horse entries F6PUQ2 and B6VA41. A 100% match indicates that the antibody should be suitable for you. If you would be interested in testing this novel species, please take a look at our Innovators Reward Program.
  3. Can you advise me the pH value for the citrate buffer?
    • For the validation of this antibody in IHC-P, we performed antigen retrieval using 0.01 M sodium citrate buffer, pH 6.0. Please note that Domyan et al 2011 from University of Wisconsin-Madison (USA) have cited the use of this antibody in IHC-P application in their experiments published in - Development (2011) 138, 971-981 Biologists site.
