  • Application notesIs unsuitable for ICC/IF.
  • Target

    • FunctionTranscription regulator involved in inner cell mass and embryonic stem (ES) cells proliferation and self-renewal. Imposes pluripotency on ES cells and prevents their differentiation towards extraembryonic endoderm and trophectoderm lineages. Blocks bone morphogenetic protein-induced mesoderm differentiation of ES cells by physically interacting with SMAD1 and interfering with the recruitment of coactivators to the active SMAD transcriptional complexes (By similarity). Acts as a transcriptional activator or repressor (By similarity). Binds optimally to the DNA consensus sequence 5'-TAAT[GT][GT]-3' or 5'-[CG][GA][CG]C[GC]ATTAN[GC]-3' (By similarity). When overexpressed, promotes cells to enter into S phase and proliferation.
    • Tissue specificityExpressed in testicular carcinoma and derived germ cell tumors (at protein level). Expressed in fetal gonads, ovary and testis. Also expressed in ovary teratocarcinoma cell line and testicular embryonic carcinoma. Not expressed in many somatic organs and oocytes.
    • Sequence similaritiesBelongs to the Nanog homeobox family.
      Contains 1 homeobox DNA-binding domain.
    • Developmental stageExpressed in embryonic stem (ES) and carcinoma (EC) cells. Expressed in inner cell mass (ICM) of the blastocyst and gonocytes between 14 and 19 weeks of gestation (at protein level). Not expressed in oocytes, unfertilized oocytes, 2-16 cell embryos and early morula (at protein level). Expressed in embryonic stem cells (ES). Expression decreases with ES differentiation.

      ab14959 recognised a band of the expected size for Nanog in mouse embryonic stem cells but not in human embryonic stem cells. Additional bands were also recognised in mouse embyonic stem cells.

      Performed under reducing conditions.

    • ab14959 staining mouse teratoma sections by IHC-P. The tissue was fixed with formaldehyde and a heat mediated antigen retrival step was performed with citric acid pH 6. Blocking of the sample was done with 1% BSA for 10 minutes at 21°C, followed by staining with ab14959 at 1/600 in TBS/BSA/azide for 2h at 21°C. A biotinylated goat anti-rabbit polyclonal antibody at 1/200 was used as the secondary antibody.

    Thank you for your response.

    This antibody has been raised using a synthetic peptide derived from residues 250 to the C-terminus of Mouse Nanog. Your question seems to be about its specificity (species-specificity) and not its sensitivity. Read More

    I am sorry to hear that you have been experiencing problems using this product in the application/species that you wish.

    Could you provide some further details of the protocol used and complete the following form (attached as a word document)...

    Thank you for your enquiry. There are at least three isotype controls you could use: normal rabbit serum (ab7487), ab27472, ab27478. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

    Thank you for your enquiry and your patience in waiting for my reply. I have compared the immunogen sequences with the sequence of bovine nanog using a ClustalW alignment. For ab14959 less than 30% of the sequence is homologous, for ab21624 the hom...
