Forensic Serology Information Page

What is Forensic Serology?According to forensic serologist Marcella Jones of www.ForensicMentor.com, forensic serology is the analysis of body fluids as they relate to forensic cases, including DNA analysis. Accordingly, the role of the forensic serologist involves:Examining evidence for the presence of body fluids e.g. blood, semen, hair, tissue, saliva, feces, and urineEvaluating evidence for potential DNA analysisEvaluating species of body fluidsPerform PCR (polymerase chain reaction) based typing of STR (short tandem repeat sequences) of genomic DNA, or mitochondrial sequence analysis of [more...]

DNA fingerprinting simplified

One of the most frequently used tools in biochemistry and biotechnology, agarose gel electrophoresis is a common forensic technique often used in genetic or DNA fingerprinting. The procedure is achieved by moving negatively charged nucleic acid molecules through a gelatinous substance known as agarose by using an electric field. Andrew, in collaboration with his father and other researchers, completed the study, which is published in the January 2008 issue the American Society of Horticultural Science’s journal HortTechnology. The youngest author ever to publish in an ASHS journal, Andrew [more...]

Variants of PCR (1)

The bacteriophage T4 DNA polymerase was also tested shortly after the first reports of PCR. It has a higher fidelity of replication than the Klenow fragment. Since it is also destroyed by heat, it has seen little use since the development of thermostable polymerases. The DNA polymerase from Thermus aquaticus (or Taq), was the first thermostable polymerase used in PCR, and is still the one most commonly used. The enzyme can be isolated from its 'native' bacterial source, or from a cloned gene expressed in E. coli. The Stoffel fragment is produced from a truncated gene for Taq polymerase, [more...]

Is there a different type of primer i have to use when running PCR ...

Question by bob oso: Is there a different type of primer i have to use when running PCR with genomic DNA compared to cDNA? Im still in school but when i run a PCR, I normally isolate RNA first then RT to cDNA and run PCR with that. This time i isolated the genomic DNA from the sample and ran PCR using the beta-actin primer i always used. Dimers were faintly visible on my gel but nothing really came up like it normally would have or should have. I was told that when running PCR with genomic DNA, a different kind of primer had to be used; one that is specific to genomic DNA. Im confused as to [more...]

HTB – Early infant diagnosis

She concluded that promising POC assays for EID today include: IQuum’s LIAT, SAMBA, CIGHT p24 and possibly CLONDIG’s viral load assay. comment This was an incredibly useful overview and it looks like we can be optimistic about having a POC test for EID in the next couple of years. Other presentations at the conference dealt with the challenges of access to EID. In the same session, Shaffiq Essajee noted that EID access has improved and in some countries more than 50% of exposed infants are tested. But infant testing is usually linked to PMTCT and if coverage is low, so is infant [more...]

Methylation Test May Aid Colon Cancer Diagnosis (CME/CE) | Discuss ...

To develop a more sensitive test for DNA methylation, investigators employed a form of technology known as BEAMing (beads, emulsion, amplification, and magnetics). They performed PCR amplification of individual DNA fragments covalently linked to magnetic beads suspended in water-based nanoparticles immersed in oil droplets. The beads contained a DNA sequence specific for exon 1 of the vimentin gene, which is hypermethylated in colon cancer. Following PCR amplification, the beads were hybridized by means of fluorescent probes specific to the state of methylation and then sorted and analyzed by [more...]

PLoS ONE: Analysis of Short Tandem Repeats by Parallel DNA Threading

Abstract TopThe majority of studies employing short tandem repeats (STRs) require investigation of several of these genetic markers. As such, we demonstrate the feasibility of the trinucleotide threading (TnT) approach for scalable analysis of STRs. The TnT method represents a parallel amplification alternative that addresses the obstacles associated with multiplex PCR. In this study, analysis of the STR fragments was performed with capillary gel electrophoresis; however, it should be possible to combine our approach with the massive 454 sequencing platform to considerably increase the [more...]

Basics: Sequencing DNA, Part 1 « Genetic Inference

However, in certain respects Sanger Sequencing is still top-of-the-range. The 4-channel capillary approach lets you sequence DNA pretty fast, and each machine can often do hundreds of reactions at once. It was these machines that first sequenced the human genome. In addition, you can sequence relatively long sequences of DNA; up to 1000 nucleotides (after that, it gets difficult to tell the difference between molecules of different sizes). We have yet to make a machine that can sequence DNA fragments of this length faster than Sanger Sequencing (yet…). The modern Sanger Sequencing machines [more...]

How Fingerprinting Helps In DNA Paternity Testing

This form of fingerprinting method is also known as DNA profiling. Using this technique, the individuals are identified on the basis of their unique DNA profiles. This DNA profiling is done by analyzing the VNTR sequences. It stands for variable number tandem repeats. This sequence is found to be different in individuals except in twins. As per the facts mentioned above, the DNA samples of the child will exhibit the similar VNTR loci as that of their parents.
