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...

Pitfalls of using organic solvents in biological systems.

The cytokines Tumour Necrosis Factoru (TNFa) and Interleukin -1p ( L I P ) are primary mediators of inflammation and sepsis. Both of these cytokines are synthesised as precursor molecules which are cleaved by converting enzymes to active molecules with an approximate molecular mass of 17kDa [I]. Recent potentially therapeutic strategies have focused on the development of small molecular weight ...

Organic co-solvents in aqueous DNA-based asymmetric catalysis.

Water-miscible organic co-solvents can be used in DNA-based catalytic asymmetric reactions at appreciable concentration without a negative effect on enantioselectivity. While the rate of the copper(II) Diels-Alder reaction is affected negatively by the presence of organic co-solvents, the copper(II) catalyzed Michael addition and Friedel-Crafts alkylation reaction are significantly faster. Addi...

Extraction of Cephalexin Using Aqueous Two-Phase Systems Composed of Cholinium Chloride and K3PO4

Cephalexin is an important antibiotic. It is very significant to determine an appropriate method for the extraction of this valuable antibiotic for industrial applications. Aiming at developing an efficient method for the extraction of cephalexin, the partitioning of cephalexin has been evaluated in aqueous two-phase system, including cholinium chloride and potassium phosphate. The effect of th...
