IN several laboratories, where whole lipid extracts are chromatographed on silicic acid in chloroform-methanol, experience has suggested the need for continuous concave gradient elution. Devices are ...

Plasmid DNA (pDNA) is a fundamental starting material for therapeutic development, including for viral vectors, mRNA therapies, and DNA vaccines. Researchers use capture methods such as anion exchange ...

With the global surge in plastic consumption, sustainable recycling has emerged as a cornerstone of environmental stewardship ...

A new, robust method for protein elution from ceramic hydroxyapatite. Hydroxyapatite is used for the fractionation and purification of a wide variety of biological molecules. At commercial scale, the ...

Since the first high performance liquid chromatographs (HPLC) hit laboratories in the 1960s, refractive index (RI) detectors have enabled the discovery of testing materials that do not possess ...

UHP-SEC has become the preferred technique for analysis of synthetic polymers. Significantly reduced consumption of sample/solvent as well as run times provides considerable time- and cost-saving ...

Several chromatographic resins are available for downstream purification. Monoclonal antibodies (mAbs) are a successful class of therapeutic products used increasingly in the past 15-20 years, but the ...
