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 ...

THE ABO grouping of dried blood smears by the absorption-elution method has already been described 1. That a similar technique can be applied to bloodstains on fabric is also known 2. This ...

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 ...

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 ...

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 ...
