The Power of LDIS

Local DNA Index System, when used to its full effect, gives local law enforcement and forensic science a valuable means to exploit the intended potential of CODIS


Next Generation Sequencing for Forensics

You can’t look at the advent of next generation DNA sequencing, the speed at which the technology is advancing, and the rate at which the cost is dropping and—with any intellectual honesty—suggest that the forensic use of DNA is going to continue with blinders to anything phenotypic.


The Future of Forensics Has Arrived: The Application of Next Generation Sequencing

The progression from Sanger-type sequencing (STS) to next generation sequencing (NGS) will further advance the regenerative sciences, personalized medicine, and forensics.


Maximizing the Power of Forensic DNA Databases with Next Generation STR Technology

Global DNA databasing trends are driving the need for cross-border data exchange, international loci-standardization, and efficient new technologies positioned to take DNA databases to a whole new level.


Touch DNA Analysis: Using The Literature To Help Answer Some Common Questions

This article is intended to update the reader on the latest touch and transfer DNA research and attempts to answer some of the most common questions that are asked regarding the topic.


Illegal Immigration

Seven years ago, the decision was made to include in a DNA database those individuals identified as being in the United States illegally. A brilliant idea for several reasons.


Inside the Black Box: Testing and Validation of a Rapid DNA Instrument

Technological advances will soon make rapid DNA testing (R-DNA) feasible and practical. But these new “lab on a chip” portable forensic DNA sampling systems also pose new challenges for the forensic DNA typing community.


Accessibility and the Backlog: Rethinking DNA Capability and Capacity

The DNA testing community must rethink its conventional mindset and reexamine traditional DNA analysis procedures.

Validation of Automated Systems For The DNA Laboratory: Perspectives From Experienced Users

Although every validation is different, the advice and experiences of others can help you develop your own validation plan.


Injunction Denied

The American Civil Liberties Union has filed its class action law suit in California challenging the implementation of that state’s arrestee DNA database legislation. Fortunately for many potential victims and for many suspects, the Federal judge deciding the preliminary injunction has ruled against the ACLU.


STR Screening: A New Tool for Forensic Labs

The purpose of a screening system is to quickly and cost-effectively determine which biological samples provide the most probative information in a large population of DNA samples.


DNA Collection and Packaging

In order to make the most of evidence, you need to know where to look for it, how to collect it, and how to package it. If you put in the effort to do the job right, you will be rewarded with an even stronger case.


Small Scale Automation in the Forensic DNA Laboratory

The availability of small automated instruments has made automation more affordable, easier to use, simpler to implement, and has also uncovered a host of additional benefits.


International Updates

DNA Initiatives around the Globe


Expert Assistant Software Enables Forensic DNA Analysts to Confidently Process More Samples

With so many improvements across the entire forensic DNA testing workflow introduced over the last five years, forensic scientists and managers are now faced with hard choices and must implement solutions that alleviate bottlenecks most quickly.


A Discussion of Automation for the Forensic DNA Laboratory

Although laboratory automation holds the promise of increasing sample throughput, in practice this does not alleviate the burden on laboratory staff. Rather it shifts the focus of the analyst’s efforts from sample preparation to sample analysis.


International Impact of Forensic DNA Technology

The advent of forensic DNA testing has had a radical and widespread impact on legal-judicial systems. The exact nature of this impact varies from nation to nation, depending on the specific needs of the nation, the existing legal-judicial system, and how DNA technology has been applied.


Improved Methods for the Elution and Extraction of Spermatozoa from Sexual Assault Swabs

The ability to perform forensic DNA analysis in criminal investigations has become an important part of solving numerous types of crime. DNA testing has become especially important in criminal cases involving sexual assault and rape.


Tackling the Backlog Using Automated Differential Extraction

A look at an automated method to overcome the limitations of standard differential extraction using phenol: chloroform or organic extraction.


Improved DNA Analysis Through Real-Time PCR Analysis

Multiplex STR analysis has long been accepted as the gold standard in the field of human identification. This method is highly informative, allowing DNA identification to be made with a high degree of accuracy.


Applying Revolutionary Technologies to DNA Extraction for Forensic Studies

Automated DNA extraction from samples eases the burden on forensic laboratories and results in more consistent processing. A number of kits specifically developed for use with these extraction techniques are expected to drastically reduce the turnaround time for forensic cases.
