Extraction of DNA from Forensic Biological Samples for Genotyping.
Biological forensic samples constitute evidence with probative organic matter. Evidence believed to contain DNA is typically processed for extraction and purification of its nucleic acid content. Forensic DNA samples are composed of two things, a tissue and the substrate it resides on. Compositionally, a sample may contain almost anything and for each, the type, integrity, and content of both t...
متن کاملDeveloping Preparation Methods for Biological Samples to Determine Trace Amounts of Heavy Metals: A Review Study
Introduction: Perpetration of samples is one of the most important stages needed for trace residue analysis of biological specimens when human exposure assessment is required. The samples preparation process makes the analyte get more purified and enriched as well as more compatible to the analysis instrument systems. The present study has concentrated on a systematic review of different articl...
متن کاملA comparative study of extraction and purification methods for environmental DNA from soil and sludge samples
An important prerequisite for a successful metagenome library construction is an efficient extraction procedure for DNA out of environmental samples. In this study we compared three indirect and four direct extraction methods, including a commercial kit, in terms of DNA yield, purity and time requirement. A special focus was set on methods which are appropriate for the extraction of environment...
متن کاملComparison of preprocessing methods and storage times for touch DNA samples
AIM To select appropriate preprocessing methods for different substrates by comparing the effects of four different preprocessing methods on touch DNA samples and to determine the effect of various storage times on the results of touch DNA sample analysis. METHOD Hand touch DNA samples were used to investigate the detection and inspection results of DNA on different substrates. Four preproces...
متن کاملDevelopmental validation of the PrepFiler Forensic DNA Extraction Kit for extraction of genomic DNA from biological samples.
The PrepFiler Forensic DNA Extraction Kit enables isolation of genomic DNA from a variety of biological samples. The kit facilitates reversible binding of DNA with magnetic particles resulting in high DNA recovery from samples with very low and high quantities of biological materials: 0.1 and 40 microL of human blood (donor 2) provided 14 and 2883 ng of DNA, respectively. Following the revised ...
