Yes / The comet assay is a sensitive method used to detect DNA damage, measuring DNA breaks and alkali labile lesions in eukaryotic cells. Here, the use of whole blood in the alkaline gel electrophoresis method is described. Two hundred and seventy blood samples from individuals were examined: 120 healthy individuals, 65 suspected or pre-cancerous individuals and 85 cancer patients. Each sample was divided into two identical volumes in different falcon tubes. The blood was prepared and stored by adding the same amount of RPMI medium and 10% DMSO. Using the Student’s t-Test, the data showed a p value = 0.59 for Olive tail moment (OTM) and 0.16 for % tail DNA, and no statistically significant differences between the two methods, with or without treatment. In conclusion, using whole blood instead of isolated lymphocytes saves time, is still very sensitive and requires less than 20 µL of blood from each individual.
