A proteomic analysis of p27kip1-binding proteins reveals a putative role in transcription regulation through RNA polymerase II interaction
|Characterization of Protein and Protein Aggregates using Temperature-controlled Hollow-Fiber Flow-FFF|
Trevor Havard, Florian Meier, Evelin Moldenhauer, Soheyl Tadjiki, Thorsten Klein
Reproducibilty Improvements in Field Flow Fractionation can be achieved on two fronts. Instrument design and control, the system used in for this poster is does not require flow controllers or switching valves and there for produces the same conditions in every case. Fractionater design, the design of the cartridges used in this poster maintain excellent conditions to maintain constant pressure at the membrane removing unwanted effects of sale relaxation above the membrane s
|Quantitative Analysis Of Pesticides In Quechers Extracts Using UPLC- and APGC- MS/MS |
Sara Stead, Simon Hird, Eimear McCall
In this study, we demonstrate sensitive, accurate and repeatable results for the analysis of pesticides in QuEChERS extracts of a selection of
commodities below the regulatory limits.
|Analytical Quality by Design (AQbD) for Developing a Validated High-Performance Thin Layer Densitometry Method for Estimating Mangiferin in Human Plasma |
Rajneet Kaur Khurana, Atul Jain, OP Katare, Bhupinder Singh
Analytical methods are highly vital at every stage of the product development starting from characterization of drug substance to its
estimation in dosage form, biological samples and stability studies. Development of analytical methods require complete understanding of the method variables to attain the superior method performance

|Combined Use of Rheometry and GPC/SEC for Characterising Ionic Polysaccharides|
John Duffy, Bernd Schaefer, Bert Postma
This poster shows how Rheometry and GPC can be complementary tools for characterising the behaviour of polysaccharides in solution
|A FastGC Proton-Transfer-Reaction Quadrupole Ion Guide Time-of-Flight (PTR-QiTOF) Mass Spectrometer|
Alfons Jordan1, Lukas Märk1, Jens Herbig1, Christian Lindinger1, Rene Gutmann1, Lukas Fischer1, Eugen Hartungen1, Simone Jürschik1, Gernot Hanel1, Philipp Sulzer1, Tilmann D. Märk1,2
In order to identify and quantify isomeric compounds independently in real-time, we introduce a novel approach where we integrate a fast GC column (“fastGC”) into a PTR-QiTOF instrument. The outstanding sensitivity of the new PTR-QiTOF (up to 4,700 cps/ppbv) is crucial for applications where time per analysis is limited, e.g. nosespace in food and flavor research. Particularly, in these fields the chemical environment is normally very complex so that a high selectivity is essential as well.
|Capillary Electrophoresis Coupled with Micro Free Flow Electrophoresis for High Speed Two Dimensional Separations of Biological Samples|
Alexander C. Johnson, Michael T. Bowser
We propose using micro free flow electrophoresis (µFFE) as a solution to the under sampling problem.
|Analysis of Polymers, Additives and Contaminates in Medical Devices using Pyrolysis-GCMS|
Pyrolysis GC-MS is a standard technique used to analyze industrial polymers. This poster will show the use of multiple temperature ramps to analyze for additives and contaminants, in addition to polymer identification, in several medical devices.
