Nanog (Early Embryo Specific Expression NK Family Gene, Embryonic Stem Cell Specific Homeobox Protein, ENK, FLJ12581, FLJ40451, Homeobox Transcription Factor Nanog, Nanog Homeobox)

NANOG is a unique variant of NK2 family of transcription factors. It is a human ortholog of mouse Nanog and consists of a highly conserved homeodomain and Trp-rich repeats. It is specifically expressed by embryonic stem cells and is crucial for second embryonic lineage determination. It works in concert with OCT-4 and SOX-2 and plays a central role in regulating pluripotency and self-renewal of ICM and ES cells. It functions independent of LIF/gp130/Stat3 pathway and prevents differentiation of ES cells to extraembryonic endoderm and trophectoderm lineages. Its expression has also been detected in embryonic carcinoma cells and germ line tumors indicating a therapeutic intervention||Applications:|Suitable for use in ELISA, Immunofluorescence, and Western Blot. Other Applications not tested.||Recommended Dilutions:|ELISA: 1:64000|Western Blot: 0.03-0.1ug/ml|Optimal dilutions to be determined by the researcher||Positive Control:|Human Ovary lysates||Storage and Stability:|May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20°C. Aliquots are stable for at least 12 monthsat -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.||Peptide Blocking:|Corresponding peptide is available for Peptide Blocking studies. See N0019-01K-P. Antibody is typically 0.5mg/ml and peptide is supplied as a 100ul pellet. When peptide is reconstituted in 200ul water, the concentration would also be 0.5mg/ml. To start, the best ratio would be 1:1 (molar excess of peptide relative to antibody when identical volumes are mixed). Mix equal volumes of peptide and antibody at the required dilution and leave at ambient temperature. It is best is to have two identical blots to be incubated with equal amount of antibody, but one with the antibody pre-adsorbed to the peptide for 20min. Then incubate and develop the two blots in parallel.
