Heavy rainfall events, increasing in frequency and intensity with climate change, impact on the quality of the water resource used for drinking-water production. Small-scale water suppliers are particularly sensitive because of their management and the related difficulties of adapting treatment to variations. Decision-support systems, based on monitoring and analytical tools, need to be developed to improve crisis-management procedures related to such events. After presenting the issues related to heavy rainfall events, the article summarizes the tools currently used for quality control of drinking water within this framework, the need for developments and other requirements.

Carbon dots (CDs) comprise a recently discovered class of strongly fluorescent, emission-color-tuning and non-blinking nanoparticles with great analytical and bioanalytical potential. Raw CDs can be obtained by laser ablation or electrochemical exfoliation of graphite, from soot, or thermal carbonization, acid dehydration or ultrasonic treatment of molecular precursors. Passivation of raw CDs makes them fluorescent and their functionalization confers reactivity towards selected targets. CDs can be excited by single-photon (ultraviolet or near-ultraviolet) and multi-photon (red or near-infrared) excitation, and their luminescence properties are due to surface defects. CDs are being proposed as bioimaging probes because they comprise non-toxic elements and are...

Automation of a Magnetic Bead Workflow for Protein Biomarker Quantification

Agilent Automation Solutions has released a new application note that demonstrates how its Bravo liquid handling system provides an efficient platform for automation of a SISCAPA Magnetic Bead Workflow for protein biomarker quantification by Mass Spectrometry.

Mass Spectrometry (MS) has become the benchmark technology for analysis of peptides based upon its ability to deliver precise quantification, near absolute structural specificity and multiplexing of measurements in a single analytical run. These advantages can be exploited in the analysis of peptides which occur in a single sequence to reveal the concentration of the parent proteins in digests of complex samples such as patient plasma or serum.

The authors of this new application note describe an automated protocol implementing SISCAPA immunoaffinity enrichment of biomarker peptides prior to quantification by MS. In the described protocol, magnetic beads coated with anti-peptide antibodies were used to bind specific target peptides from tryptic digests of plasma and serum samples, after which the beads were washed to remove unbound peptides, and the bound, purified peptides were eluted in small volumes for injection and analysis in an LC/MS/MS system.  Stable isotope labeled versions of the same peptides was used as internal standards to enable accurate quantification.  The Agilent Bravo automated protocol for this application enabled SISCAPA processing of 96 samples in less than 30 minutes, less than half the time required by traditional manual methods.

Daylight Solutions Grows the Aries™ Line of High-Power,

Daylight Solutions, Inc., a leading manufacturer of advanced molecular detection, spectroscopic, and high-power illumination solutions based on quantum cascade and other technologies, announced today the expansion of the Aries™ Series of highpower, multi-wavelength mid-IR lasers. Earlier this year Daylight Solutions introduced the first in the product line, the Aries™-100 air-cooled 2 W laser. The Aries™ commercial product line has now been expanded to include the Aries™-200, -400, and -700 products. The modularity of the Aries™ family of products can now provide the end user with customizable performance in wavelength and power. Our customers can now choose to populate one, two, four, or seven laser “sockets” with any wavelength and power that Daylight offers. Populating all seven sockets in the Aries™-700 can provide over 10 W of cw, air-cooled mid-IR laser power.

“The flexibility and performance of the Aries™ product family is beyond anything available on the market to date,” says Michael Radunsky, Product Marketing Manager for Daylight Solutions’ scientific products. “These turn-key systems can be configured for high power at a single wavelength or to deliver up to seven different wavelengths simultaneously and collinearly.” The Aries™-100 is CDRH approved and is ready for lab use. The higher models in the series are OEM laser systems that are ready for integration. Radunsky continues, “The SPIE Defense, Security, and Sensing Symposia and Exhibition is an excellent venue for the announcement of this new product line, as the Aries™ series serves this community well. These lasers are already finding applications in stand-off detection, free space communication, infrared countermeasures,

thermal imaging, and scene generation.”

Wavelengths ranging from 2 to 13 μm are available in the Aries™ products. The higher models in the series are also highly ruggedized. Standard performance includes operation within an ambient temperature range of 15 to 40 °C. However, they can also be specified to operate over a much wider range of operating temperatures, ranging from -40 to +70 °C. Aries™ has also been tested for shake and vibration resistance. Optical fiber delivery is also available as an option. “Releasing an additional three models simultaneously for the Aries™ series is a good accomplishment for our team,” states Paul Larson, President of Daylight Solutions. “The flexibility of these models enable applications in multiple markets.”

Peristaltic Pump Simplifies Challenging Liquid Handling Tasks

INTEGRA has launched a new version of its popular DOSE IT peristaltic pump  with enhanced functionality enabling laboratories to now undertake even challenging liquid handling tasks.

Some liquid handling applications require more than just simple pumping.  The new DOSE IT "CUSTOMIZE" software mode allows users to create their own personalized liquid handling protocols. Up to 20 consecutive dispensing and aspirating steps can be defined. A wide range of settable parameters, such as volume, flow rate and repetitions, can be assigned to each step. In addition, the flow rate can be set to ramp up or down to the target speed, thus avoiding foaming, splashing or unwanted turbulences during dispensing.

Applications that have benefited from the new DOSE IT customize mode include gentle filling of density gradient tubes by slowly increasing the flow rate, coating Petri dishes by adding and removing coating solution and preparing serial dilutions by having an air gap between sample and the diluent, to mention but a few.  Simple to set-up and implement the scope for optimised liquid handling protocols using the new DOSE IT is almost limitless

DOSE IT is an intuitive programmable peristaltic pump that simplifies the dispensing of cell culture media, buffers and other solutions for volumes ranging from 0.1mL to 2500mL. DOSE It features a very small footprint and weighs only 3.5Kg making it a perfect device for bench-top or in-hood dispensing applications. Programming the DOSE IT is fast and easy through a multilingual user interface (English, Spanish, German, French and Italian). The instrument's pump head accommodates the use of different tubing diameters (1-8mm) allowing a wide range of volumes to be dispensed with optimal speed and precision. An built-in print capability supports the capture of program details for record keeping and quality control. Many accessories are available to support a variety of dispensing applications.

New Solid State ChIP Technology for Epigenetics

Porvair Filtration Group has launched a new web microsite (www.chromatrap.com) dedicated to providing detailed information on its ground breaking solid state Chromatin Immunoprecipitation (ChIP) technology for the Epigenetics market. The web microsite provides an informative background as to what ChIP technology is about and introduces the new solid state approach pioneered by researchers at Porvair Filtration Group.

Porvair's new Chromatrap® Pro-A technology depends on a porous inert polymer called BioVyon™. Each Chromatrap® spin column contains a BioVyon™ disc with the internal pore structure covalently bonded with Protein A (BioVyon™ Protein A). Complex mixtures containing the chromatin fragments tagged with the antibody of choice are flowed through the column assisted by centrifugation. The column retains the chromatin of interest whilst unwanted debris is flushed away. Purified chromatin is eluted ready for downstream processing and analysis.

A collaborative case study on the site compares the Chromatrap protocol with results from using a Protein G Magnetic Beads technique. Under optimal conditions, the Chromatrap protocol resulted in a 25.5 fold increase in the percentage DNA pull-down using the exact same sample of MCF7 breast cancer cells, targeting the RNA polymerase II protein bound to the GAPDH target gene.

A further independent case study compares Porvair Chromatrap technology with alternative traditional ChIP methods (Sepharose and Dynabeads). In this study Chromatrap columns were shown to provide a greater level of enrichment of the DNA of interest due to low levels of background binding compared to specific antibody binding. Also the DNA pull down (percentage input) was significantly higher for the Chromatrap columns than for the other matrices in these assays.

For further information or to discuss evaluating the new Chromatrap™ ChIP assay technique please contact Porvair Filtration Group on +44-1489-864330 / Kevin.Quinlan@chromatrap.com

CHN Microanalysis: A Key Technique for Sample Characterisation

A white paper written by Exeter Analytical describes how CHN microanalysis provides a powerful and straightforward method for determining whether a sample is pure - a key aspect of sample characterisation.

The paper discuss how by providing a precise and accurate analysis of the percentage Carbon, Hydrogen and Nitrogen in an organic sample - CHN microanalysis can compliment techniques such as Mass Spectrometry (MS) and Nuclear Magnetic Resonance (NMR) Spectrometry, thus enhancing the reliability of your analytical results.

Many organisations today benefit from the relative ease with which NMR can be used to determine target compound validity or elucidate the structure of an unknown in the absence of crystal data.  Similarly Mass spectrometry is a powerful analytical technique used by many laboratories to identify unknown compounds, quantify known materials, and elucidate the molecular structure and chemical composition of organic and inorganic substances.

However both NMR and MS techniques have limitations when it comes to assessing sample purity.  If the impurity in the sample is inorganic (e.g. silica from sample purification by flash chromatography using an acidified mobile phase) then it will be invisible to traditional 1H, 13C or 15N NMR techniques.  Likewise organic contaminants present at less than c. 1% of the sample are typically invisible to NMR.   Data is provided showing how CHN analysis can help determine low levels of impurities. Further data is provided showing how CHN microanalysis can be used to determine the presence of residual solvent in samples at levels that has little or no effect on the Mass or NMR spectra.

A NEW Generation of SpinColumns™

SpinColumns™, by Harvard Apparatus, are ideal for quickly desalting, removing unbound markers, and for purification of Proteins, Peptides and DNA.
Harvard Apparatus’ NEW Generation of SpinColumns™ are designed for purification of small samples (10µl to 150µl) in either single column or high-throughput 96-well or 384-well formats.  Centrifugal force drives the separation process in the SpinColumns™.

SpinColumns™ are offered pre-filled with a wide selection of chromatographic materials including gel-filtration, ion-exchange, silica-based reverse (C18) and normal phase materials.  Specific materials such as charcoal, cellulose, and IMAC contained by frits and/or caps are also available.

Columns can be pre-filled with custom materials based on customer requests.

Simple to use, place the SpinColumns™ into a centrifuge tube or plate rotator and spin for two minutes to separate your samples.  The column material binds and purifies the sample according to size, shape, chemical composition, charge or other physiochemical properties.

Harvard Apparatus offers six sizes of SpinColumns™ to fit your specific application.
