EXCLUSIVE: How They Caught Grim Sleeper Suspect Lonnie David ...

Sources tell Los Angeles Weekly that the serial killer was caught through familial DNA testing after his son was arrested and had to give up a DNA swab. A month ago, LAPD detective Dennis Kilcoyne said LAPD was going to try another controversial "familial DNA" matching probe, testing against 1 million samples in the California felon database to find the killer's cousin, brother or uncle. "At least it brings a little bit of closure," Laverne Peters, the mother of victim Janecia Peters, told LA Weekly today. "It is very good news for me. I don't know whether to cry or scream." The science of [more...]

The HPV Test - Web Resource

The site provides information about testing for the sexually transmitted human papillomavirus. The website was created by the Digene Corporation, the maker of the HC2 High-Risk HPV DNA Test, which is used to screen for 13 high-risk types of HPV which have been associated with the development of cervical cancer. The test is primarily for women over 30, who are considered to be at greater risk for developing cervical cancer. I would generally warn you to be cautious when using websites created by or for drug/biotechnology companies because they have a product to sell, a good general guideline [more...]

Biosensors: Morpholino offers you more

Molecular biologists and geneticists often use DNA microarrays to detect DNA, measure gene expression levels and detect the single-nucleotide polymorphisms that are responsible for various genetic diseases. A DNA microarray has tens of thousands of biosensors on its surface; each biosensor contains a short DNA fragment, known as a probe, for recognizing DNA targets. Ideally, the DNA biosensor should have high sensitivity (the ability to detect very low concentrations of targets), high specificity (the ability to distinguish the difference between similar targets) and high stability (the [more...]

Reveo's direct DNA sequencing using tunneling microscopy « The ...

Reveo is developing an ambitious technology to stretch out and deposit taut DNA on conductive surfaces for electronic base detection using one or more STM tips and tunneling current measurements. The linearization and deposition of nucleic acid sequences will likely be done using molecular combing. Reveo’s approach requires atomically flat and positively charged substrate surfaces (e.g. self-assembled monolayers on gold substrates or treated graphite substrates). In addition to molecular combing, Reveo has proposed other methods to linearize DNA, including electrophoretic and hydrodynamic [more...]

Lab earns two technology transfer awards in regional competition

Each probe tests for a particular sequence of DNA and small groups of probes can be used to check for specific bacteria or viruses. The current LLMDA has been used to test for more than 2,000 viruses and 900 bacteria. The next generation LLMDA in development will expand that capability to 6,000 viruses, 2,000 bacteria as well as fungi and protozoa organisms. Any probe that detects its specific sequence will fluoresce, which will be read by a scanner and may indicate presence of that organism. The LLMDA team analyzed the safety of rotavirus vaccines and in one case detected a benign pig [more...]

20000 Genes Under the Brain: Genes->Brain->Man

To assess gene expression in each small bit of tissue, researchers expose its RNA to a gene chip, or DNA microarray. These small devices are coated with clusters of identical DNA molecules, called probes, within separate areas. Each probe binds to the RNA of a specific gene—the one that contains a complementary set of chemical units, or bases. In a DNA molecule, the base adenine (A) sticks to thymine (T), and guanine (G) pairs with cytosine (C). Thus, the sequence that would bind to the strand illustrated above is (from top to bottom): T, C, C, T, G, C, A. In this way, a chip records which [more...]

Neandertal DNA and Proteins

With the completion of the Neandertal genome by the team of Dr. Svante Paabo and a closer look at their proteins by Gregory Hannon’s team at CSHL, scientists reveal incredible similarities between Neandertals and humans. Neandertals, the extinct species of what are most likely our closest relatives, lived on earth at the same time as our human ancestors but died out about 30,000 years ago. With the sequence of their genome now complete, we can compare the DNA to humans and chimpanzees to learn more about what makes humans unique as a species. The discovery of fossils is an exciting link to [more...]

Johne's disease : Diagnosis | The farm's guide

There is a DNA probe recently approved to detect Mycobacterium paratuberculosis in bovine feces. Fecal culture has been the standard test used; it can demonstrate and quantify the presence of the bacteria and, therefore, identify the shedding animal. It is, however, time consuming, expensive to perform, and not widely available. In cattle, cultures usually need to be incubated eight to 16 weeks before growth of the organism is evident. Further-more, animals must be shedding bacteria to be detected. Only a very small proportion of the young stock may be shedding bacteria, and some older [more...]

Article Snack » Where To Learn More About Proof Of Paternity

Using the coming of DNA testing these days, paternity can be established with almost 100% accuracy. Except for identical twins, your DNA is as distinctive as your fingerprint. DNA (deoxyribonucleic acid) denotes your genetic makeup like the color of your hair and eyes, skin color, height, and others. The youngster gets 50% of his DNA from his mum and also the other half derives from his dad. Comparing the child’s DNA with that in the biological mom will get rid of the genes inherited from her. What remains are the DNA of the father. A comparison of probes between the father, mother and [more...]

Truth probing unethical

That is why many judges will both allow DNA fingerprinting to be admissible as evidence with its one-in-a-billion error and reject polygraph exam results. Even if a flawless test could be created, the use of a brain wave test on interrogation targets is also wrong and should not be done.

Southern hybridizations with a 1.3-kb BamHI clone, internal to the 6.0-kb Pst I fragment, as a probe revealed two configurations of 6.0-kb homologous sequences in the sterile cytoplasm; one of the configurations was lost upon reversion or restoration. Mitochondrial DNA rearrangement has thus been observed upon restoration by a nuclear restorer gene in this CMS [more...]
