Can somebody give me a proper protocol for isolating DNA from the pellet obtained after the harvested cells from cell culture done by cytogenetic method. The pellet is in 3:1 fixative (Clarke's solution)?
I am aware of the PCI method from EDTA blood but in my case the WBC is suspended in methanol:glacial acetic acid (3:1). I obt ained it from the regular cytogenetics method. Can anybody tell me how to start from this step and continue with the PCI step?
Well, u need to centrifuge cell suspension and get rid of supernatant followed by consecutive washing of the pallet with PBS solution three to four times. PBS should be cold before use.
