  • Function
    Binding of FREAC-3 and FREAC-4 to their cognate sites results in bending of the DNA at an angle of 80-90 degrees.
  • Tissue specificity
    Expressed in all tissues and cell lines examined.
  • Involvement in disease
    Defects in FOXC1 are the cause of Axenfeld-Rieger syndrome type 3 (RIEG3) [MIM:602482]; also known as Axenfeld-Rieger syndrome (ARS) or Axenfeld syndrome or Axenfeld anomaly. It is characterized by posterior corneal embryotoxon, prominent Schwalbe line and iris adhesion to the Schwalbe line. Other features may be hypertelorism (wide spacing of the eyes), hypoplasia of the malar bones, congenital absence of some teeth and mental retardation. When associated with tooth anomalies, the disorder is known as Rieger syndrome. Glaucoma is a progressive blinding condition that occurs in approximately half of patients with Axenfeld-Rieger malformations.
    Defects in FOXC1 are the cause of iridogoniodysgenesis anomaly (IGDA) [MIM:601631]. IGDA is an autosomal dominant phenotype characterized by iris hypoplasia, goniodysgenesis, and juvenile glaucoma.
    Defects in FOXC1 are a cause of Peters anomaly (PAN) [MIM:604229]. Peters anomaly consists of a central corneal leukoma, absence of the posterior corneal stroma and Descemet membrane, and a variable degree of iris and lenticular attachments to the central aspect of the posterior cornea.

Thank you for contacting us.

I am sorry to hear you have been having problems seeing any staining with the Anti-FOXC1 antibody (ab5079). We have as yet not tried this antibody in staining in frozen sections so we do not yet know how it might perform. I would say there are a few things that may be worth trying to see if the staining improves:

1. I would try a higher concentration of antibody, down to 1/50 to see if any signal is observed.

2. You may want to consider an alternative fixative, such as acetone, methanol or ethanol. This will eliminate the need to perform an antigen retrieval step.

3. Antigen retrieval of frozen sections can be a little tricky. I would refer to the following reference for further information:

http://www.ncbi.nlm.nih.gov/sites/entrez?Db=pubmed&Cmd=Search&Term=%22Yamashita%20S%22%5BAuthor%5D&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVAbstractPlusDrugs1, http://www.ncbi.nlm.nih.gov/sites/entrez?Db=pubmed&Cmd=Search&Term=%22Okada%20Y%22%5BAuthor%5D&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVAbstractPlusDrugs1. Application of heat induced antigen retrieval to aldehyde fixed fresh frozen sections. http://www.jhc.org/. 2005 Nov;53(11):1421-32.

Both Sodium citrate (pH 6.0) and Tris-EDTA (pH 9.0) buffers have been used successfully in antigen retrieval of paraffin embedded sections with this antibody. The recipe for these buffers can be found in the following protocol book:


4. As the antigen is found in the nucleus, it may be worth trying stronger permiabilisation instead of antigen retrieval. You could try applying 0.1% Triton in PBS for 10 minutes prior to applying the antibody. This will partially dissolve the nuclear membrane to allow the antibody to move through.

The TNB buffer is just a simple tris buffer, 0.10 M Tris.HCl, 0.15 M NaCl, 0.5% milk. The buffer you are using (PBS with milk blocking) should be fine for the staining.

I hope this information has been of help. We would be very interested to hear how the results progress.

I am afraid that we don't yet have any positive data on this antibody. We also can't do test samples on these Fast-Track reagents - they are available early before we have proper data on a trial basis. We have had a number of sales recently with this antibody, but we are struggling to get in touch with the end users. I am sorry I can't give you any better information. We put these antibodies out because they might be useful to researchers who are willing to take a chance, but we can't provide the normal guarantee that they will work.

Dear Fred ab5079 is actually an Investigative grade antibody which means it has only been characterised by ELISA. On the datasheet it states that we have seen no signal on Western blot as yet and the lower price of the antibody reflects that. We have released the antibody because it is of interest to our customers. We do apologise because this was incorrectly labelled and Western blot was stated as tested on the datasheet, but this was a mistake on our part which has been corrected.
