It would, but my lab has minimal funding and no experience in karyotyping (or related techniques like FISH). The A7r5 cell-line was derived decades ago, so I was hoping that someone has already carried out such a method on them. The only answer I would like is 'male' or 'female' (even better with a citation for the experimental evidence).
Forget karyotyping, too much work. PCR for the SRY gene will do the trick, only male cells have this. Alternatively if you have RNA available, a RT-PCR for the XIST female specific transcript will also work.
PS. my wife went to UCC and we got married there. Good luck!
