Study Demonstrates Gene Expression Microarrays are Comparable and Reproducible

... followed a common protocol for allsteps of sample preparation and microarray analysis and the resultinggene expression profiles were analyzed and compared.Sample correlation within each lab was extremely high; microarray datafrom the RNA samples had the highest correlation values, followed bythe cell lines, and...

Spider Venom Could Yield Eco-Friendly Insecticides

...viruses and small-molecule mimics of the toxins in preparation for field trials. The Blue Mountains funnel-web spider is not the only source of insect-specific neurotoxins. Thousands of spider species yet to be studied represent an untapped reservoir of diverse insecticidal compounds that could do more than con...

Disease diagnosis, biodefense among UH chemical research projects

...The long-term goal of this research focuses on the preparation of nanometer-sized arrays of sensor molecules that are relevant to early-stage disease diagnosis, when treatment is still an option. Cai also is an author on four other papers that will be presented at the ACS meeting. # Dar-Chone Chow, assistant pr...

Affymetrix Launches New Globin-Reduction Kits and Protocol Developed with PreAnalytiX

Comprehensive biodefense text published

...d in the 25 chapters is an extensive discussion of preparation and military support for possible acts of bioterrorism, medical count ermeasures, emerging threats and future preparation, and development of diagnostic tests for identifying biological warfare pathogens. Intended for researchers, physicians, and po...

Researchers pioneer new gene therapy technique using natural repair process

...e takes advantage of the healthy copies created in preparation for division, and uses them as a template to repair the break in the DNA strands. In the new gene therapy technique, researchers took advantage of homologous recombination by introducing a man-made enzyme that recognizes and binds DNA at specific po...

Life detection instrument passes key test on road to Mars

...d improvements at JPL over the next seven years in preparation for its long-range mission. In fact, she and Mathies hope she's the one looking at MOA data when it's finally radioed back from the Red Planet. "When I first started this project, I had seen photos of the Martian surface and possible signs of water,...

Small worm yields big clue on muscle receptor action

...and Stephen Von Stetina. Richmond has developed a preparation for cutting open the microscopic nematode to record muscle responses when acetylcholine is applied. Using this preparation, Richmond was still getting muscle contraction when acetylcholine was applied to worms lacking any of five receptor subunits kn...

Scientists succeed in cloning human embryos from eggs matured in the lab

...ernal and paternal chromosomes start to pair up in preparation for the first cell division. In the case of these oocytes they had undergone a pseudo-fertilisation because the pronuclei were derived from whole foreign nuclei, each one with a complete set of homologous [matching] chromosomes, instead of from sperm...

Invitrogen Launches i-Path -- A Unique Systems Biology Platform at BIO 2005

Researchers develop new method for facile identification of proteins in bacterial cells

...The technique avoids elaborate conventional sample preparation steps by coaxing the cells into mass production of the protein the researchers wish to analyze. "Finding a specific target in a mixture of hundreds of proteins can be likened to finding the proverbial needle in the haystack; this task can be perform...

Woods Hole Research Center plans controlled burn in Amazon rainforest

Scientists show that tick-borne flaviviruses use a novel mechanism to evade host defenses

...ne flaviviruses to emerge on other continents." In preparation for such a development, Dr. Fauci notes that two other NIAID laboratories have similar flavivirus studies under way, and the three groups are building on the discoveries of each other. Dr. Bloom says that all flaviviruses have a similar genomic stru...

Tagging pathogens with synthetic DNA 'barcodes'

...obarcode detection system does not require complex preparation of a sample and can be applied to living cells. The technology could be used in genomic research, clinical diagnosis, drug testing, environmental monitoring and monitoring for biological terrorism, they suggest. Further details on "tree-shaped" DNA ...

3D Atlas Will Help Navigate The Spinal Cord

...search. Professor Paxinos is a world leader in the preparation of brain atlases, being the author of atlases of human, monkey, rat and mouse brains used world-wide by neuroscientists in all areas. As a geographic map to a traveller, a map of the spinal cord is needed by scientists studying the spinal cord of hu...

New tooth enamel dating technique could help identify disaster victims

... were done at the Karolinska Institute, and sample preparation and accelerator mass spectrometry analysis was done at Lawrence Livermore. The enamel dating technique doesn't work for people born before 1943, because all of their teeth would have been formed before testing began in 1955. In their Nature paper, ...

Optimizing cell therapy against tumors is a balancing ACT

...icacy may depend on different T cell selection and preparation strategies" and these findings indicate that a pragmatic strategy for ACT is to keep the in vitro T cell expansion phase as short as possible to keep them naïve. These findings are important for development of improved adoptive immunotherapy approach...

Method slashes quantum dot costs by 80 percent

... - the least expensive solvent used in quantum dot preparation today - account for about 90 percent costs of raw materials. Heat-transfer fluids - stable, heat-resistant oils that are used to move heat between processing units at chemical plants - can cost up to seven times less than ODE. Replacing ODE with the...
