I want to study cytogenetics from blood samples. I have never done this type of study so I want to know if it is possible to do cytogenetic study from blood samples which were stored for a year?
Usually, for storage one needs to isolate the mononuclear cells and freeze them in a DMSO-Medium-FCS mixture and keep them in liquid nitrogen. In this way the cells remain vital and may be thawed and cultured for chromosome harvesting several years later.
