|Concentration and Mixing Effects on the Production of Amine Hydrochloride Salts in a Confined Impinging Jet Reactor|
Navid F. Ershad, Archie Eaglesham, Don H. Jones and Suzanne M. Kresta
Results show that different AHC salts can be formed under different process conditions.
|A mix-and-read cell-based assay for antibody screening against Epithelial Growth Factor Receptor |
Wayne P Bowen, David Onley, Paul Wylie, Diana Caracino and Tristan Cope
Here we present a sensitive robust, mix-and-read method for the screening of antibodies against cell surface proteins. With its simple operation, no-wash format, and high sensitivity, this new method is well-suited for high throughput antibody screening.
|"Some Like it Hot" - Continuous Flow Chemistry at High Temperatures and Pressures|
David Obermayer, Bernhard Gutmann, Toma N. Glasnov, Tahseen Razzaq, Markus Damm and C. Oliver Kappe
More and more recently published chemistry examples in glass-chip- and Teflon based microreactors begin to exploit the possibility of superheating solvents for process intensification leading to drastically shortened reaction times.
|Quality Standards for 14C API for use in human clinical studies|
I Shaw, G Johnston, K Dare, D Dams
The Good Manufacturing Practice (GMP) state that the active pharmaceutical ingredient (API) intended for use in early stage clinical trials should be of "suitable" quality. The Clinic Ready quality standard ensures that the API is synthesised with all the appropriate documentation to facilitate QP release of the final IMP for guman clinical dosing.
|Microwave chemistry in SiC Reaction Vials|
D. Obermayer, B. Gutmann, B. Reichart, C. O. Kappe
Using novel SiC-technology to mimic conventional heated autoclave experiments.
|Organic azide synthesis in microreactors: from optimization to lab scale production|
Pieter J. Nieuwland, Bo Hanssen, Kaspar Koch, Paul Janssen, Marielle M.E. Delville, Anton Lunshof and Floris P.J.T. Rutjes
The formation of benzyl azide by diazotransfer to benzyl amine was screened and subsequently scaled up using continuous flow chemistry.
|Automated Sample Pretreatment of Environmental|
Bernard Sheldon,1 Rosanne Slingsby,1 and Rida Al-Horr2
Matrix elimination is a method of sample preparation that removes
certain matrix species from a sample, typically by specifically binding
matrix species to a solid phase. Interfering compounds can be removed
before the analyte determination, thus improving the quality of results as
well as lengthening the lifetime of consumables such as columns.
|Five noncovalent peptidic ligands show different affinity rankings in solution and gas phase|
Andrey Dyachenko , Michael Goldflam , Marta Vilaseca , Ernest Giralt
Stability of noncovalent complexes of VEGF protein with 5 peptidic ligands is studied. Experiments were conducted in solution (NMR CSP, ITC) and in gas phase (CID TOF MS). Each ligand differs from others in chirality of one amino acid. It was shown, that trend of stability of the studied noncovalent complexes is reversed in the gas phase relatively to the solution. An explanation of this behavior is presented.
|Study of volumetric oxygen transfer coefficient in a Taylor vortex flow bioreactor|
Patrícia Ap. Santiago, Cláudio A. T. Suazo, Roberto C. Giordano
An inadequate transfer of oxygen can lead to rapid changes in cell physiology, metabolism, and cell death. In this work, the KLa is evaluated in a Taylor vortex flow bioreactor and a mass transfer correlation is proposed. The experimental conditions employed were: rotational Reynolds number between 244 and 2928, airflow rates varying from 80 mL.min-1 to 550 mL.min-1 and used culture medium DMEM.
