| Abstract: | The use of Qiagen QIAamp and QIAshredder for extracting DNA from envelope flaps and stamps is reported. The stamps or flaps can be added directly to extraction solutions and the DNA is bound to a spin column containing a silicon membrane for washing prior to elution. DNA extracted from four stamps and four envelope flaps was amplified and analyzed using a multiplex PCR system. Complete DNA profiles were obtained from five samples. |
