Organic/aqueous Two Phase Microflow for Biological Sample Preparation
Organic-aqueous liquid (phenol) extraction is one of many standard techniques to efficiently purify DNA directly from cells. With effective mixing, the cell components naturally distribute themselves into the two fluid phases in order to minimize interaction energies of the biological components with the surrounding solvents. The membrane and protein partition into the organic phase while the D...

A panorama of sample preparation methods has been composed from 481 references, with a highlight of some promising methods fast developed during recent years and a somewhat brief introduction on most of the well-developed methods. All the samples were commonly referred to molecular composition, being extendable to particles including cells but not to organs, tissues and larger bodies. Some crit...

As food legislation calls for methods of control, reliable analytical methods have to be available to make the enforcement of regulations possible. The reliability of analysis data can be improved through the use of methods that fulfil certain performance criteria (demonstrated in interlaboratory studies) and the application of analytical quality assurance (AQA) procedures is recommended, inclu...
متن کاملpreparation and characterization of dexamethasone microemulsion based on pseudoternary phase diagram
results the results showed that the maximum oil was incorporated in microemulsion system that contained surfactant to cosurfactant ratio of 4:1. the mean droplet size range of microemulsion formulation was in the range of 5.09 to 159 nm, and its refractory index (ri) and ph were 1.44 and 7, respectively. viscosity range was 57-226 cps. drug release profile showed that 48.18% of the drug release...

Sample preparation. The structure of CoPOM and ZnPOM have been previously reported. The complexes used in this work have been synthesized using the procedure described for the analogous MnII compound but using Co(SO4) and Zn(SO4) instead of Mn(SO4). HiPCo SWNTs were purchased from Carbon Inc. and purified by the gas phase method. All the solutions were prepared using Millipore water. Functional...
