Continuous Purification of mRNA Produced by In Vitro Transcription Using High Performance Countercurrent Membrane Purification. [PDF]

open access: yesBiotechnol Bioeng
ABSTRACT Messenger ribonucleic acid (mRNA) therapeutics produced by in vitro transcription must be purified to remove residual enzymes and free nucleotides. This study examines the use of high‐performance countercurrent membrane purification (HPCMP) for the purification of mRNA therapeutics based on differences in the rate of diffusion across ...

Prediction of Elution Profiles in Countercurrent Chromatography With a Linear Loss of Stationary Phase. [PDF]

open access: yesJ Sep Sci
A common challenge in reliably predicting elution profiles in countercurrent chromatography using the ProMISE2 software is a persistent loss of stationary phase (i.e., bleeding). This drawback can be overcome by a simple calibration method in the case of linear bleeding.

Purification and characterization of phthalanilide-lipid complexes from tissues

open access: yesJournal of Lipid Research, 1966
What appears to be a new class of phospholipids has been isolated from dog brain in the form of complexes with a substituted phthalanilide. The complexes were extracted by chloroform-methanol and purified by countercurrent distribution in solvent systems
