Applied Biosystems Advances Forensic Science with the World's First Commercial Chemistry for Analyzing Degraded DNA
Applied Biosystems (NYSE: ABI), an Applera Corporation business, today
announced the world’s first commercially
available reagent kit for generating genetic profiles from aged,
compromised, or damaged DNA samples. The new AmpFlSTR® MiniFiler™ PCR
Amplification Kit was developed in response to the growing backlog of
samples recovered from crime scene investigations and other instances of
DNA collection in which the samples could not previously be identified
because of poor sample quantity or quality. The new kit is expected to
enable an increase in the number of solved criminal cases, in addition
to aiding in the investigation of missing person occurrences.
The new MiniFiler kit has already successfully contributed information
to a high profile criminal investigation regarding the identification of
the remains of a young woman whose decomposed body was found buried in a
shallow grave near Deer Creek, Montana in 1984. The case of Debbie Deer
Creek - the name given to the Jane Doe by law
enforcement officials - languished for more
than two decades as forensic scientists did not have the ability to
determine her identity because forensic DNA technology could not
effectively analyze the samples recovered from her skeletal remains.
An unexpected break in the case occurred, however, when the University
of North Texas System, Center for Human Identification began to test the
MiniFiler kit. Dr. Arthur Eisenberg, professor and director of the
Department of Pathology and Human Identification, was able to analyze
Debbie Deer Creek’s degraded DNA using
MiniFiler in conjunction with other DNA testing methods to positively
identify her as Marcella Bachmann, a young woman who had been missing
for 22 years.
Using the CODIS+mito National Missing Persons DNA Database, a "cold
hit” occurred with a family reference sample
provided by the King County Sheriff’s Office
in Washington state. Family reference samples were being collected for
young women who had disappeared from 1982-1998 in an attempt to identify
other potential victims of the "Green River
Serial Killer,” Gary Ridgway. The results
from the MiniFiler kit were instrumental in confirming the
identification of Ms. Bachmann, bringing closure to this long-standing
cold case. Law enforcement officials from Montana are convinced that
Debbie Deer Creek was the victim of Wayne Nance, an eight-time serial
killer.
"In some of the most heartbreaking and
horrendous cases, we used to have to accept that some DNA samples simply
could not be tested,” said Dr. Eisenberg. "The
new MiniFiler kit allows us to analyze samples that previously provided
limited or no results. With this new technology, we expect that we will
be able to increasingly identify human remains and solve crimes that
would not have been possible with other systems.”
Different factors, such as sample age and environmental factors, affect
the degradation of DNA. As DNA degrades, the volume of testable material
becomes smaller and more difficult to analyze. In some cases, sample
material may contain impurities that limit –
or inhibit – the ability to properly amplify
the sample. As DNA becomes inhibited, samples are less likely to produce
results.
MiniFiler applies a new approach to standard DNA technology by
shortening the fragments used to amplify DNA. These shortened regions
are known as short tandem repeat (STR) regions or miniSTR technology.
They allow analysis of very small fragments of DNA. STRs are repeated
DNA sequences that are variable in length and are widespread throughout
the human genome. Such variability allows discrimination among
individuals in a population, which is useful for identification in
forensic cases.
The chemistry of the MiniFiler kit complements other Applied Biosystems
forensic DNA testing kits, including the Identifiler®,
Profiler Plus® and
COfiler® and SGM Plus®
kits. For example, if a degraded sample amplified with the Identifiler
kit is missing seven of the 15 loci normally amplified by the kit in a
forensic case, the MiniFiler kit complements it by amplifying the same
sample to provide results for the seven loci that were not successful.
Working together, the two kits have the potential to provide a full
identification profile from damaged DNA.
Applied Biosystems expects that the MiniFiler kit will enable
laboratories to obtain more complete identification profiles from DNA
samples, which can be uploaded to DNA databases and used to assist
forensic investigations.
"The ability to analyze degraded DNA gives
forensic scientists a powerful tool for getting better results from a
broader range of DNA samples that have been impacted by either the
environment or by time,” said Leonard Klevan,
Ph.D, president for Applied Biosystems’
applied markets division. "We expect this
advancement to help solve more crimes, reopen unsolved cold cases,
exonerate the wrongly accused and help identify missing persons.”

About Applera Corporation and Applied Biosystems
Applera Corporation consists of two operating groups. The Applied
Biosystems Group serves the life science industry and research community
by developing and marketing instrument-based systems, consumables,
software, and services. Customers use these tools to analyze nucleic
acids (DNA and RNA), small molecules, and proteins to make scientific
discoveries and develop new pharmaceuticals. Applied Biosystems’
products also serve the needs of some markets outside of life science
research, which we refer to as "applied
markets,” such as the fields of: human
identity testing (forensic and paternity testing); biosecurity, which
refers to products needed in response to the threat of biological
terrorism and other malicious, accidental, and natural biological
dangers; and quality and safety testing, for example in food and the
environment. Applied Biosystems is headquartered in Foster City, CA, and
reported sales of $1.9 billion during fiscal 2006. The Celera Group is
primarily a molecular diagnostics business that is using proprietary
genomics and proteomics discovery platforms to identify and validate
novel diagnostic markers, and is developing diagnostic products based on
these markers as well as other known markers. Celera maintains a
strategic alliance with Abbott for the development and commercialization
of molecular, or nucleic acid-based, diagnostic products, and it is also
developing new diagnostic products outside of this alliance. Through its
genomics and proteomics research efforts, Celera is also discovering and
validating therapeutic targets, and it is seeking strategic partnerships
to develop therapeutic products based on these discovered targets.
