Description: The Btjce monoclonal antibody reacts with the transcription factor Sox2, a member of the SOX (sex determining region Y -related HMG (High Mobility Group) Box) family of proteins. Sox family members play a role in early organ development, and in particular, Sox2 is essential for regulating genes that control normal mammalian embryogenesis. Sox2 and family member Sox3 are expressed as early as the preimplantation and epiblast stages respectively. Later expression is restricted to the neuroepithelium. Sox2 has been shown to be necessary for maintaining self-renewal and pluripotency of mouse and human embryonic stem (ES) cells (ESC). Oct4 (POU5F1), Klf4, c-myc, and Sox2 were the original four factors used to reprogram differentiated mouse and human cells to induced pluripotent stem cells (iPSC).
Expression of Sox2 is tightly regulated and recent studies have demonstrated that small changes in the levels of Sox2 in ES cells can trigger differentiation into multiple cell types. Sox2 expression is not limited to ES cells, it is also essential for early neurogenesis where its expression becomes restricted to the neural plate, and later to neural stem cells where it functions to suppress neural differentiation. Sox2 in combination with other stem cell markers can be used to characterize stem cell populations. Ectopic expression of Sox2 has been associated with multiple cancer types including colorectal and breast.
Applications Reported: This btjce antibody has been reported for use in intracellular staining followed by flow cytometric analysis and immunocytochemistry.
Applications Tested: This btjce antibody has been tested by immunocyochemstry of fixed and permeabilized F9 cells. This can be used at less than or equal to 10 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
This btjce has also been tested by intracellular staining and flow cytometric analysis using the Foxp3/Transcription Factor Buffer and protocol. Please refer to intracellular Staining Protocol on Best Protocol web page - Protocol B: One-step protocol for intracellular (nuclear) proteins. This can be used at less than or equal to 0.125 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

SOX2 is an intronless gene encoding a member of the SRY-related HMG-box (SOX) family of transcription factors involved in the regulation of embryonic development and in the determination of cell fate. The product of the SOX2 gene is required for stem-cell maintenance in the central nervous system, and also regulates gene expression in the stomach. The SOX2 gene lies within an intron of another gene called SOX2 overlapping transcript (SOX2OT). Further, SOX2 protein may act as a transcriptional activator after forming a protein complex with other proteins. Mutations in the SOX2 gene have been associated with bilateral anophthalmia, a severe form of structural eye malformation, optic nerve hypoplasia and syndromic microphthalmia.
