ChIP: 10ul per ChIP
ChIP-Seq: 10ul each
ICC/IF: 1:200 dilution
WB: 1:500-1:1,000 dilution ChIP-Seq validation was performed's Epigenetics Services.
Chromatin Immunoprecipitation (ChIP)
(Sox2 antibody (pAb) tested by ChIP-Seq. ChIP was performed using the ChIP-IT High Sensitivity Kit with 30 ug of chromatin from undifferentiated hESC cells and 7 ul of antibody. ChIP DNA was sequenced on the Illumina HiSeq and 10 million sequence tags were mapped to identify Sox2 binding sites. The image shows binding across a region of chromosome 7. You can view the complete data set in the UCSC Genome Browser, starting at this specific location, here.)
Immunofluorescence (IF)
(Sox2 antibody (pAb) tested by Immunofluorescence. Mouse embryonic stem cells (mESCs) grown on mouse embryonic fibroblast feeder cells (MEFs) were fixed with 4% paraformaldehyde for 10 minutes at room temperature. Cells were then permeabilized and blocked by incubating with Blocking Solution containing 5% serum/0.1% Triton X-100 in D-PBS for 2 hours at room temperature. Cells were then incubated with Sox2 antibody at 1:200 dilution overnight at 4 degree C, washed with D-PBS, and incubated for 2 hours at room temperature with goat anti-mouse Cy3 secondary antibody at 1:250 dilution. Cells were visualized using a Zeiss fluorescent microscope at 20X magnification. Images show that Sox2 antibody specifically stains mESC colonies and does not stain MEFs. Absence of Sox2 staining in a subset of cells within the colonies suggests differentiation. Scale bars, 100 ?m.)
Background: Sox2 (SRY related HMG BOX gene 2) is a DNA binding transcription factor and a member of the SOX family of proteins. SOX proteins have an HMG box that binds DNA. Sox2 forms a complex with Oct-4 and controls the expression of a number of genes involved in embryonic. Sox2 is critical for early embryogenesis and for embryonic stem cell pluripotency and thus can serve as a stem cell marker. Overexpression of Sox2 (along with Oct-4, KLF4 and c-Myc) can transform mouse fibroblasts into a state resembling embryonic stem cells (ES cells), referred to as Induced Pluripotency. Defects in Sox2 are the cause of microphthalmia syndromic type 3.
NCBI and Uniprot Product Information
NCBI Description
This intronless gene encodes 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 this gene is required for stem-cell maintenance in the central nervous system, and also regulates gene expression in the stomach. Mutations in this gene have been associated with optic nerve hypoplasia and with syndromic microphthalmia, a severe form of structural eye malformation. This gene lies within an intron of another gene called SOX2 overlapping transcript (SOX2OT). [provided by RefSeq, Jul 2008]
