DNA integrity and size range assessed by agarose gel electrophoresis. a Lane M DNA high molecular weight marker, lane 1 positive control (DNA extracted from whole blood), lanes 2–6 5 DNA prepared from the same blood sample and absorbed on different FS, and lanes 7–11 DNA of 5 different blood samples absorbed on FS. b Lane M DNA molecular weight marker, lanes 1–10 10 μL of albumin-amplified products of DNA extracted from different FS samples, lane NTC “no template control” DNA sample extracted from FS without absorbed blood
