Product Information
Product Usage Information
Directions for Use:A. Chromatin Immunoprecipitation:ChIP formulated antibodies have been tested and optimized using the SimpleChIP® Enzymatic Chromatin IP Kits (#9002 and #9003). Antibodies should be used at a dilution of 1:50 in a 500 μl ChIP reaction containing 10 to 15 μg of chromatin (4x106 cells). For the SimpleChIP® Enzymatic Chromatin IP protocol, please see the web page for this product at www.cellsignal.com.B. Quantification of DNA by qPCR:1. Label the appropriate number of PCR tubes or PCR plates compatible with the model of real-time PCR machine to be used. PCR reactions should be performed in duplicate and should include a tube with no DNA to control for contamination, and a serial dilution of a 2% total input chromatin DNA (undiluted, 1:5, 1:25, 1:125), which is used to create a standard curve and determine amplification efficiency.2. Add 2 μl of the appropriate ChIP DNA sample to each tube or well of the PCR plate.3. Prepare a master PCR reaction mix as described below. Add enough reagents for two extra reactions to account for loss of volume. Add 18 μl of the master PCR reaction mix to each PCR reaction tube or well of the PCR plate.Reagent Volume for 1 PCR Reaction (20 μl)
Nuclease-free H2O 6 μl
5 μM SimpleChIP® Primers 2 μl
2X SYBR-Green Reaction Mix 10 μl
4. Start the following PCR reaction program:
a. Initial Denaturation 95°C for 3 min
b. Denaturation 95°C for 15 sec
c. Anneal and Extension *Primer-specific temp. for 60 sec
d. Repeat steps b and c for a total of 40 cycles.*65 °C Anneal/Extension for SimpleChIP® Human Oct-4 Promoter Primers*60 °C Anneal/Extension for SimpleChIP® Human α Satellite Repeat Primers5. Analyze quantitative PCR results using software provided with the real-time PCR machine.
Storage
Primers are supplied in nuclease-free water at a concentration of 5 μM and should be stored at -20°C.

Source / Purification
Oct-4 (C30A3C1) XP® Rabbit mAb (ChIP Formulated) is produced by immunizing animals with recombinant protein specific to the amino terminus of human Oct-4A protein. Sox2 (D6D9) XP® Rabbit mAb (ChIP Formulated) is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly179 of human Sox2 protein. Nanog (D73G4) XP® Rabbit mAb (ChIP Formulated) is produced by immunizing animals with a synthetic peptide corresponding to the amino terminus of human Nanog protein.
Product Description
Background
Embryonic stem cells are pluripotent cells derived from the inner cell mass (ICM) of the mammalian blastocyst. Pluripotent cells are capable of indefinite self-renewing expansion in culture and can differentiate into cell types of all three germ layers: endoderm, ectoderm and mesoderm. This pluripotent state is a property shared by embryonic stem (ES) cells, embryonic carcinoma and induced pluripotent stem (iPS) cells. Oct-4, Sox2 and Nanog are key transcriptional regulators that are highly expressed in pluripotent cells (1). Together they form a master transcriptional regulatory network that maintains cells in a pluripotent state (2,3). Over-expression of Oct-4 and Sox2 along with Klf4 and c-Myc can induce pluripotency in both mouse and human somatic cells, highlighting their roles as key regulators of the transcriptional network necessary for self-renewal and pluripotency (4,5). It has also been demonstrated that overexpression of Oct-4, Sox2, Nanog and Lin28 can induce pluripotency in human somatic cells (6). Chromatin immunoprecipitation (ChIP) is a powerful technique that can be used to identify Oct-4, Sox2 and Nanog target genes in a given population of pluripotent cells (2,3,7-9). In addition, ChIP can be used to characterize changes in target gene occupancy that occur during induction of iPS cells from somatic cells, or differentiation of pluripotent cells into different cell lineages.
