Countercurrent distribution of ribonucleic acids. IV

Biochimica et Biophysica Acta (BBA) - Specialized Section on Nucleic Acids and Related Subjects, 1962
Abstract RNA which has been prepared from rat liver by phenol-water or phenol-naphthalene 1,5-disulphonate methods can be fractionated by countercurrent distribution in two-phase systems of 2-alkoxyethanols and 1.25 M phosphate containing N , N -dibutylaminoethanol.

Phase equilibria and countercurrent distribution

Journal of the American Oil Chemists' Society, 1968
AbstractTernary diagrams for methyl oleate/hexane/acetonitrile and methyl palmitate/hexane/acetonitrile systems were constructed from equilibria data obtained at 20.0 and 30.4C. The diagrams varied significantly with temperature; both systems showed expanded regions of immiscibility at the lower temperature. Both the partition coefficient of the methyl

[16] Countercurrent distribution

1967
Publisher Summary Countercurrent distribution is a method for the separation of protein subunits that offers the possibility of using conditions that cannot be achieved with separation methods such as electrophoresis or ion-exchange chromatography.

Nonideal Phenomena in Countercurrent Distribution

Separation Science, 1969
Abstract An equation is presented that predicts the number of inputs required to produce a step-function (frontal) output in countercurrent distribution (CCD). When a portion of both phases is transported during experiments, the published equations for CCD are inappropriate.

Countercurrent Distribution of Colchicine and some Derivatives *

Journal of the American Pharmaceutical Association (Scientific ed.), 1953
Abstract A method for the determination of the composition of a binary mixture based on partition coefficients is reported. Where a significant difference exists in the partition coefficients of the two components for a given solvent system, an equation is presented which permits composition analyses where other methods may not be applicable.

Fractionation and countercurrent distribution of ribonucleic acid

Biochimica et Biophysica Acta, 1960
Abstract 1. 1. RNA has been prepared from rat and chicken liver by phenol-water and phenol-naphthalene-1,5-disulphonate (NDS) methids. The RNA prepared by the phenol-NDS method appears to be less degraded than RNA isolated by phenol-water. 2. 2.

Partition by Countercurrent Distribution (CCD)

2003
A crucial step in many biochemical studies is the separation and purification of the individual structures of interest. For cells, cell organelles, and membrane fragments, the use of aqueous two-phase partition has become an important tool. The basis for separation in these phase systems is the surface properties of the material, and the method ...
