“Nano-scissors?laser shows precise surgical capability
)is quite a challenge; its about 1 mm in length. A research team fromthe University of Texas at Austin developed a method of laser-assistedsurgery to work on these little beasts, being able to section a singleaxon (the "arms" of a neuron) with g...Enzyme shown to help protect genomic stability
Genomes throughout the animal kingdom and beyond are characterized by extensive segments that are inactive, lengthy stretches of DNA containing multiple genes that are closed to gene transcription. Scientists believe one reason for this broad gene silencing is the vital need for genomic stability, for protection against unwanted recombinations of genetic material or other disruptions of the genom...Jumping gene helps explain immune system's abilities
A team led by Johns Hopkins scientists hasfound the first clear evidence that the process behind the human immunesystem's remarkable ability to recognize and respond to a milliondifferent proteins might have originated from a family of genes whoseonly apparent function is to jump around in genetic material. essentially cut...Low level of extinction during ice age linked to adaptability
A Johns Hopkins University graduate student may have figured out why rates of extinction were so low for many of the major groups of marine life during one of the greatest ice ages of them all, which occurred from about 330 million to 290 million years ago, late in the Paleozoic Era. The likely answer: because those aquatic life forms that did survive during this era were singularly equipp...Brain-injury rehabilitation depends on acetylcholine circuitry
The ability of the brain to recover from such injury as stroke or trauma depends on a particular circuitry of neurons that "talk" to one another using the brain chemical acetylcholine, researchers led by James Conner and Mark Tuszynski in the Neural repair Group at UCSD have discovered. Their finding in rats could help enhance rehabilitation to recover from such injuries by leading to the develop...Arabidopsis 2 Oligo Microarray Kit (V2), 22K from Agilent Technologies
Description:The Arabidopsis 2 Oligo Microarray Kit (V2), 22K is useful for investigating plant organ functions, growth stages, and stress response. Each microarray contains content derived from the ATH1 v. 3 database of The Institute for Genomic Research (TIGR) and represents 21,500 genes.

Description:The GrabIt™ Kits are designed for the study of protein:protein interactions from eukaryotic cells using a pull-down method. Proteins that interact with GST•Tag™, S•Tag™, or T7•Tag fusion proteins are copurified using affinity resins for the tags, and the complexes are retained on a spin filter. The complexes are eluted with sample buffer in prepar...Arabidopsis microRNA Microarray from LC Sciences
Description:Microarrays designed for genome-wide microRNA expression profiling and built on the flexible and powerful Paraflo microfluidic on-chip synthesis platform. These microarrays are available as part of our comprehensive microRNA Expression Profiling Service. The Arabidopsis microRNA Microarray contains all known arabidopsis microRNAs (74 unique mature sequences). The co...Agilent Arabidopsis 3 Oligo Microarray Kit from Agilent Technologies
Description:Arabidopsis thaliana is the first higher plant to be fully sequenced and annotated, and serves as the primary model organism for gene expression research in higher plants. The content on this microarray is derived from the ATH1 v.5 database of The Institute for Genomic Research (TIGR) and from the Arabidopsis MPSS database at the University of Delaware. Nearly 40,000 features represents 28,500 ge...Rabbit Anti-ABIN-2 Polyclonal Antibody, Unconjugated from BioVision

Disposables such as Eppendorf Tubes and pipette tips are frequently exposed to chemical reactions and they must withstand the various kinds of stress and strain encountered in everyday laboratory work (such as centrifuging and autoclaving). The stability level of these products is largely determined by the materials fr...Chemical Stability of the Brinkmann Bottletop Dispenser and the Brinkmann Bottletop Buret
Bottletop Dispenser and the Brinkmann Bottletop Buret Bottletop dispensers are used in the lab for dispensing a wide range of different solvents from glass or stainless steel containers. These dispensers have to meet various requirements. For example, they must not give...Eppendorf Mastercycler ABI Big Dye Sequencing Protocol

A study conducted by Dr. Michael Brent, an associate professor of computer science at the Washington University in St. Louis, gives us an insight into the way children understand and speak languages at such a tender age.These findings were presented at the annual meeting of the American association for the advancement of science in San Francisco.For years the ability of children to pick u...Test-tube babies show no emotional problems
Babies born with the help of fertility treatment grow into emotionally and socially well-adjusted children, according to new research. The world's first study that followed in-vitro, or test tube, babies to the brink of adolescence showed that youngsters who had been conceived through fertility treatments do not suffer any more psychological problems than other children. Since L...Babies of the deaf communicate
Healthy, hearing babies born to deaf parents and exposed mainly to sign language use their hands to silently ``babble,'' indicating that babbling serves as an important precursor to learning a language. Dr. Laura-Ann Petitto, a professor in the departments of Psychological & Brain Sciences and Education at Dartmouth College in Hanover, New Hampshire believes, that this must be the key...Food Habits Could Change Your Genes
Eating specific food could change your genes, say researchers after success in a rodent study.Researchers Moshe Szyf, Michael Meaney and colleagues at McGill University in Montreal have found that nutrients // and supplements changed genetics by switching on or off certain genes in rodents, reports science portal EurekAlert. The new research was conducted in the lines of a two-year-o...Graefe Strabismus Hook - Non-Magnetic
