Ion Chromatography ICP-Q-MS for the Detection of Arsenic Species in Apple Juice
Thermo Scientific
Interest in the determination of Arsenic species in fruit juices has been triggered by recent media reports in the United States claiming that some apple juices may contain high amounts of Arsenic. Inorganic forms of Arsenic (As3+ and As5+) are highly toxic, whereas the organic forms (e.g. arsenobetaine) are not considered toxic. A robust IC-ICP-MS system was developed and shown to be a highly selective and sensitive technique for determination of trace element species.
High Content Analysis of Neural Stem Cell Expansion and Differentiation
Molecular Devices
Automated assay methods for monitoring neural stem cell expansion and differentiation using stem cell derived neural cell lines and high content imaging systems have been described.
Modeling Disposition of Sotalol following Intravenous and Oral Administration in Healthy Adult Subjects
Simulations Plus
Sotalol is a non specific adrenergic beta-antagonist that is used in the treatment of life-threatening arrhythmia. Its absorption, distribution and systemic PK or, collectively, ‘disposition’ was modeled and simulated using GastroPlus™ v7.0. Biopharmaceutical properties were obtained from in silico predictions and in vitro measurements.
Predicting hERG Potassium Channel Affinity with Artificial Neural Network Ensembles
Simulations Plus
Modeling hERG inhibition has gained significant popularity since 2005, when the FDA recognized the correlation between hERG inhibition and a prolonged QT interval by issuing guidance for the evaluation of new non-antiarrythmic drugs against the hERG channel.Long QT syndrome or LQTS is a risk factor for ventricular tachyarrhythmias and sudden death.
Predicting Sites of Metabolism with Artificial Neural Network Ensembles
Simulations Plus
Hepatic first-pass metabolism of many drugs and pro drugs plays a key role in their oral bioavailability. The human cytochrome P450 enzymes are responsible for the metabolism of most drugs. Knowledge of likely sites of metabolic attack in a drug molecule can aid in designing out unwanted metabolic liabilities early on in the drug discovery process, as well as in the design of pro drugs where metabolic transformation is desired.
Influenza A (H1N1) Transmission in Andhra Pradesh, India
MNR Medical college
The spread of highly pathogenic influenza A (H1N1) virus has posed a serious threat to human community in several regions of the world including India, and has created an immediate need for effective prevention strategies against the pandemicity of the disease. The present study gives a comprehensive picture of spread of H1N1 cases in Andhra Pradesh during 2009 and 2010, from the daily notification data.
Hot Start Amplification using OligoBeads via Gradual Release of Bound Primers

Two-Dimensional HPLC Combined with On-Line SPE for Determination of Sudan Dyes I–IV in Chili Oil
Dionex - Part of Thermo Fisher Scientific
Although use of Sudan dyes in food is restricted, they are nevertheless sometimes added to foods to improve the appearance and command a higher price. Because Sudan dyes may create health problems such as genotoxic and carcinogenic effects, concerns over contamination of Sudan dyes has increased awareness and testing for these compounds.
Fast Determination of Anthocyanins in Pomegranate Juice
Thermo - Part
Due to their strong antioxidant properties, anthocyanins are of considerable interest. Pomegranate juice (PJ) has been reported to contain 3× more antioxidant activity than green tea. Due to the high demand for pomegranates, adulteration of PJ has become widespread. Manufacturers have attempted to extend the limited supply by blending with filler ingredients such as cane sugar, corn syrup sweeteners, and lower-quality juices containing sorbitol, malic acid, and sucrose.
Analysis of Fruit Juice Adulterated with Medium Invert Sugar from Beets
Dionex - Part of Thermo Fisher Scientific
Fruit juice adulteration presents an economic and regulatory problem. The United States orange juice industry estimates that orange juice sales gross more than one billion dollars annually.

Contaminant bovine IgG assay
Molecular Devices
Fetal calf serum containing bovine IgG is commonly used in mammalian cell culture media for the production of recombinant pharmaceuticals. During the purification process of a recombinant pharmaceutical, bovine IgG may be copurified with the product, and may represent a biological hazard for clinical use. Therefore, it may be necessary to assay for contaminant bovine IgG in a final product originating from mammalian cells.
Applications of rapid immunoassays (FAST ILA) in cell culture/fermentation and process development using the Threshold System
Molecular Devices
Accurate measurement of the concentration of a biological product is important in bioreactor/fermenter monitoring, downstream processing and final product quality control. Currently, electrophoretic, chromatographic and immunochemical methods are the most commonly used. These three methods are currently used in combination to provide the desired sample information.
Dual-Glo Luciferase Reporter-Gene Assay on the SpectraMax M5, LMax II384 and Analyst GT Microplate Readers
Molecular Devices
Reporter-gene assays are used to study eukaryotic gene expression. Dual genetic reporters are commonly used in transient transfections of cultured cells to minimize experimental variability. Recently, Promega introduced a Dual-Glo Lucoferase assay system which replaced the outdated ‘flash’ assays used previously. Ensuring both genetic reporters have different substrate requirements enables them to be detected using a single reaction mixture.
Sequence-Specific DNA Assay
Molecular Devices
The Threshold® system from Molecular Devices, together with the Immuno Ligand Assay (ILA) kit can be used to measure specific DNA sequences. Biotinylated or fluorescienated oligonucleotide probes, specific to the target sequence, anneal to the digested target DNA creating a probe-target hybrid which can then be detected and quantified against a standard curve, with pleasing results.
Measurement of Proteasome Inhibition in Live Cells in Molecular Devices Microplate Fluorometers
Molecular Devices
The proteasome is a massive protein complex which can recognize and bind targeted proteins, and inject them into the central core where the proteins are successively degraded into short peptides. Whereas protein synthesis is well-understood after decades of study, major advances in our knowledge of protein degradation have occurred only in the last two decades.
Recording of ICRAC in RBL-1 Cells on the PatchXpress 7000A Automated Patch Clamp System
Molecular Devices
Calcium release-activated calcium (CRAC) channels play an important role in intracellular Ca2+ homeostasis. Like other store-operated calcium channels, currents through the CRAC channel (ICRAC) are activated by depletion of calcium in the endoplasmic reticulum (ER) and serve the purpose of slowly replenishing the ER with Ca2+.
