FIG 7 Detection limit for blood genomic samples. A, B are 1 ng/µl blood 1 and blood 2 samples, respectively, tested 5 times independently (n = 5). C, D. 0.1 ng/µl of blood 1 and blood 2 samples, respectively, independently repeated 5 times (n = 5). E, F. Repeated test difference analysis of Tm values for blood 1 and blood 2 samples, respectively. WT, wild-type; MT, mutant. NTC, negative control.
