Chromatography has long been the workhorse of high-resolution bioseparation. It is the most commonly used technique for preparative work, and is second only to electrophoresis in analysis. Most ...

Nobel Laureate Linus Pauling, Ph.D., predicted in 1939 that hydrogen bonding would prove to be more significant in the field of biology than any other type of chemical bond. His prediction has been ...

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 ...

Gas chromatography is an innovative approach to separating and quantitating vaporized compounds through the use of an inert carrier gas. Gas chromatography functions according to similar principles as ...

Supercritical fluids show certain properties that are used to advantage in chromatographic separations: No liquid/gas phase boundary and therefore no surface tension Solute solubility increases with ...

Size exclusion chromatography (SEC) is a proven method for molecular weight (MW or molar mass) measurement of proteins, typically involving comparison of the column retention volume of a sample ...
