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.

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 ...

Profiling and Isolation of Ten Rare Branched-Chain Alkylresorcinols in Quinoa

open access: yesMolecules, 2023
Alkylresorcinols (∑ARs) are bioactive lipid compounds predominantly found in cereals. These amphiphilic compounds exist in a high structural diversity and can be divided into two main groups, i.e., 5-alkylresorcinols (ARs) and 2-methyl-5-alkylresorcinols
