Next-generation sequencing provides a more powerful look at the foundational DNA marker of human identification, short tandem repeats (STRs). Unlike traditional length-based analyses, sequencing STRs uncovers more information from the same DNA samples. If you've ever been forced to choose between STR panels when analyzing a precious sample, had a perfect DNA profile but still needed more discriminatory power, or wished for a more efficient way to analyze routine and complex samples, then register for this webinar.

| | | | |  DNA ‘fingerprints’ are signature pieces of DNA that are specific to an individual, and therefore, can be used to identify a person. Nearly every cell in the human body contains DNA. While almost all of the human DNA sequence is identical to every other person on the planet, 0.1% of it is unique to the individual. This 0.1% equates to roughly three million base pairs and the unique patterns amongst these base pairs distinguish an individual from another. | | | | |  The ability to separate proteins and other biological components mean that electrophoresis is popular in the field of forensics, particularly in the analysis of unknown samples. | | | | |  Cell culture forensics emerged as a result of the widespread contamination that plagued the work of scientists around the world during the 1970s and 1980s. Recent advances in cell identification technologies have created a powerful forensic approach aimed at ensuring that these contamination issues are not repeated. | | | | |  For the past decade, considerable discussion has been made on the extent to which cognitive bias can impact how decisions are made in forensics. Although cognitive bias can arise naturally for a number of different reasons, significant consequences - including incorrect conclusions, overstatements, and impartial decisions - may occur. | |
