Lequan Yu,Xin Yang,Jing Qin,Pheng-Ann Hengd block protocol. However, obtaining the mitotic chromosomes is often hampered under several circumstances. As a result, cytogenetic analysis will be sometimes difficult or even impossible in such cases. Premature chromosome condensation (PCC) is an alternative method that has proved to be a unique

Cells are irradiated with a defined dose of UV light leading to the formation of DNA lesions and incubated in the dark to allow repair. About 90% of the photoprodu

Multiparameter analysis of γH2AX immunofluorescence by flow or laser-scanning cytometry allows one to measure extent of DNA damage in individual cells and to correlate it with t
