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 ...

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 ...

Fast protein liquid chromatography (FPLC) is, as the term implies, an effective (fast) liquid chromatography technique for the separation of protein molecules. The term also implies that the mobile ...

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 ...

Ion exchange chromatography (IEX) is a versatile and widely used technique for separating biomolecules based on charge. It plays a critical role in protein purification in research and ...

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 ...

Gas chromatography (GC) is an older analytical technique that is still widely used today. It is a technique that can be used with both inorganic and organic analytes, but the one requirement is that ...

There is a growing demand for high purity chemicals within the technical, life science and fine chemical industries. As new synthetic routes are discovered and purity requirements increase, the demand ...
