When we did the same thing with HeLa cells we got good results, but not with our own blood sample. I'm not getting what went wrong. I'm expecting chromosome from white blood cells of the blood.
For Human karyotyping you require different media and more over you need to follow the harvesting procedure is different from others like cell lines ,stem cells,AM etc and you need to collect blood in Heparinised vacutainer tube not in EDTA vacutainer that is mandatory
