The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use at an assay dependent concentration.
ICC 1/100.
Flow Cyt Use at an assay dependent concentration.

ab171870 - Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.

ICC/IF 1/1000.
WB 1/200. Detects a band of approximately 38 kDa (predicted molecular weight: 34 kDa).

Some users report a stronger signal after blocking and diluting antibodies with 1% BSA instead of 5% milk.

Sandwich ELISA Use a concentration of 0.5 µg/ml. For sandwich ELISA, use this antibody as Detection at 0.5 µg/ml with Mouse monoclonal [1E6C4] to Nanog (ab76586) as Capture.
ChIP Use at an assay dependent concentration. PubMed: 18710938

Target

  • Function
    Transcription 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 specificity
    Expressed 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 similarities
    Belongs to the Nanog homeobox family.
    Contains 1 homeobox DNA-binding domain.
  • Developmental stage
    Expressed 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.

  • ab21624 staining Nanog in Human testis tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and blocked with 10% serum for 1 hour at 20°C; antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody (1/500 in PBS) for 12 hours at 4°C. A Biotin-conjugated Goat anti-rabbit polyclonal (1/200) was used as the secondary antibody.

Question
Answer

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 homology is 50%, and for ab21603 the epitope is not known but the overall sequence homology is approximately 50%. The end result in my opinion is that the homology is not high enough for any of these antibodies to cross-react with bovine nanog. You would want to see a higher degree of homology to have any confidence that these antibodies would cross-react with bovine nanog. I hope this information helps, please do not hesitate to contact us if you need any more advice or information,
