UCSB scientists probe sea floor venting to gain understanding of early life on Earth
New keys to understanding the evolution of life on Earth may be found in the microbes and minerals vented from below the ocean floor, say scientists at the University of California, Santa Barbara. The UCSB scientists are making new contributions to this field of inquiry in their studies of seafloor hydrothermal fluid discharge into the Earth's oceans, which has been occurring ever since t...Nano-Probes Allow an Inside Look at Cell Nuclei
Nanotechnology may be in its infancy, but biologists may soon use it to watch the inner workings of a living cell like never before. Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Lawrence Livermore National Laboratory have developed a way to sneak nano-sized probes inside cell nuclei where they can track life's fundamental processes, such a...Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin
Nano-sized particles embedded with bright, light-emitting molecules have enabled researchers to visualize a tumor more than one centimeter below the skin surface using only infrared light. A team of chemists, bioengineers and medical researchers based at the University of Pennsylvania and the University of Minnesota has lodged fluorescent materials called porphyrins within the surface of a polyme...Products containing specific probes for detecting alternative splice forms protected
ExonHit Therapeutics, today announced the grant of a major patent, US # 6,881,571, by the United States Patent and Trademark Office on microarray products allowing the specific detection of mRNAs produced by alternative splicing, covering microarrays optimised for the discovery of alternative RNA splicing events. The patent protects the probe configuration of a unique set of five oligonucleotides...Duke engineers develop new 3-D cardiac imaging probe
Biomedical engineers at Duke University's Pratt School of Engineering have created a new three-dimensional ultrasound cardiac imaging probe. Inserted inside the esophagus, the probe creates a picture of the whole heart in the time it takes for current ultrasound technology to image a single heart cross section. The new probe has considerable potential not only for evaluating the condition...SYBR Green II RNA gel stain*10,000X concentrate in DMSO* from Molecular Probes (Invitrogen)
Description:is a sensitive nucleic acid gel stain that has bright fluorescence when bound to RNA and low background in gels, making it ideal for use with either formaldehyde/agarose or polyacrylamide gels using laser scanners or standard UV transilluminators. One mL stains 100 minigels. A 500 µL unit size (S-7564) and a special packaging (S-7586) are available....SYBR Green II RNA gel stain*10,000X concentrate in DMSO* from Molecular Probes (Invitrogen)
Description:is a sensitive nucleic acid gel stain that has bright fluorescence when bound to RNA and low background in gels, making it ideal for use with either formaldehyde/agarose or polyacrylamide gels using laser scanners or standard UV transilluminators. 500 µL stains 50 minigels. A 1 mL unit size (S-7568) and a special packaging (S-7586) are available....adenosine 5'-O-(3-thiotriphosphate), BODIPY FL conjugated/tagged from Molecular Probes (Invitrogen)
Description:BODIPY FL ATP-Gamma-S binds to ATP-binding proteins. To create this fluorescent nucleotide the BODIPY FL fluorophore was linked through the Gamma-thiol of ATP-Gamma-S. In addition to its potential use for binding studies the BODIPY FL ATP-Gamma-S thioether is an important new substrate for Fhit a member of the histidine triad superfamily of nucleotide-binding proteins....SlowFade Antifade Kit from Molecular Probes (Invitrogen)
Description:The active ingredient in Molecular Probes. SlowFadeAntifade Kits is 1,4-diazabicyclo[2.2.2]octane (DABCO), which appears to act as a free radical scavenger that extends useful fluorescence emission. Our original SlowFade formulation (S-2828) was designed to reduce the fading rate of fluorescein to almost zero (Figure 1); it does, however, decrease fluorescein.s fluorescence intensity. Because it...New Microarray Labeling Kit for Preparing cDNA Probes

Sorge Rebecca L. Mullinax Stratagene Phenogenex Nucleic acid micro...RNase Protection Assay (RPA) Using DIG-Labeled RNA Probes
The ribonuclease protection assay (RPA) is a highly sensitiveand specific method for the detection and quantitationof mRNA species. The assay was made possibleby the discovery and characterization of bacteriophageencodedDNA-dependent RNA polymerases (SP6, T7,and T3)....Detection of mRNAs on Cryosections of the Cardiovascular System Using DIG-Labeled RNA Probes
The following protocol was optimized from a protocolusing 35S-labeled RNA probes [1, 2]. In research studies,it enables detection of the expression of rare mRNAs inthe cardiovascular system (e.g., of the proinflammatorycytokine granulocyte macrophage colony stimulating...New scalpel probes into cancer
A smart scalpel which is able to detect the presence of cancer cells beneath layers skin, blood and muscle have been developed by US researchers. The bottle-top sized microcavity laser developed by the US department of Energy will enable surgeons to operate more accurately on tumours without cutting large amounts of tissue.// This device could detect which cells were cancerou...The Bio-probe –“ Boon to women ?
With the new device called the Bio probe being developed, screening women for cervical cancer could be made lot easier.” // The Bio-probe has to be inserted into the vagina, and the woman herself can do it. The probe remains inserted for 10 seconds while it measures electrical resistance. It is so small that women would feel more comfortable using the device than with than taking up the...Research Fraud By Doctor – Probe Demanded
A leading health activist in Kerala has called for a government probe into an Uttar Pradesh-based doctor, in the dock for research fraud by reputed publications, The Lancet and the British Medical Journal. // "The credibility of the medical research community of our country will be questioned unless the Indian Council for Medical Research (ICMR) or a government-appointed body investigate...Tamiflu Shortage Can Be Better Handled By Combining It With Probenecid
Drug Synergism refers to the enhancement in action or effect of a particular drug than the individual effect of both the drugs combined. The phenomenon could be exploited in the present scenario where the avian bird flu is posing a serious threat across different regions of the globe. // Tamiflu is a prescribed drug for seasonal flu, because it will be a first line of defense if the H...Three In One Ultrasound Probe For 3-D Imaging Of Heart And Tissue Destruction Developed
