Study of preservation solutions by comparing Dimethyl Sulfoxide – Sodium Chloride (DMSO-Nacl) and ethanol as storage for soft tissue samples

DNA profiling for victim identification is one of the most important aspects to consider in mass disaster identification. Proper collection, storage and preservation procedures are crucial to reduce the effect of the degradation. Therefore, the aim of this study is to assess the potential of 20%DMSO...
