    ab5188 staining CDYL in human male kidney, showing a distinct and strong staining pattern in tubuli and glomeruli cells. Paraffin embedded human skin tissue was incubated with ab5188 (1/1000 dilution) for 30 mins at room temperature. Antigen retrieval was performed by heat induction in citrate buffer pH 6.

    ab5188 was tested in a tissue microarray (TMA) containing a wide range of normal and cancer tissues as well as a cell microarray consisting of a range of commonly used, well characterised human cell lines. Further results for this antibody can be found at www.proteinatlas.org

Thank you for your reply. Unfortunately, I am not an expert in this field and I have not been able to find any publications relating to the expression profiles in mice stem cells. I am not aware of a particular protein or antibody that would recognise a target uniquely expressed from the Y chromosome in stem cells at least. The majority of genes expressed from the Y chromosome also have X homologs e.g. Smcy and its X homolog Smcx. However, we do have an Sry antibody which is the sex determing factor although I am under the impression that it is uniquely expressed in testes. I would think that the best way to identify male from female cells would be to perform DNA FISH using a commercially available kit and probing X and Y loci. e.g. Males would have green and red foci whereas females would have two green foci. I hope this information helps. Please do not hesitate to contact me should you require further assistance.

Thank you for your enquiry. The peptide sequence used to raise this antibody was a synthetic peptide conjugated to KLH derived from within residues 301-314 of Mouse CDYL, corresponding to sequence TGVTAGKRKFIDDR. In reponse to your question it will depend on whether you wish to localize male human or mouse stem cells transplanted into female mice. Human CDYL is expressed from the Y chromosome but according to http://www.pnas.org/cgi/content/abstract/99/13/8707, murine CDYL is autosomal. I have also found out that in mice it is expressed as 2 transcripts: a ubiquitous transcript and a highly expressed testis-specific transcript. Therefore if you wish to use it as a marker it will depend on the level of expression in the ubiquitous transcript. Unfortunately I could not determine whether it's expression was sex specific, such details were not present on the EXPASY database. I hope that this information helps. Please do not hesitate to contact me should you require further assistance.
