Size exclusion chromatography (SEC) separates components of a sample on the basis of their molecular size. Differential exclusion or inclusion of the molecules is achieved via filtration through a gel ...

Exclusion chromatography can be used to separate molecules on the basis of size 1,2. The technique described here, which uses gel filtration to separate high-molecular-weight DNA from smaller ...

RNA synthesis using in vitro transcription by phage T7 RNA polymerase allows preparation of milligram quantities of RNA for biochemical, biophysical and structural investigations. Previous ...

The bulk physical properties such as strength and toughness of materials such as synthetic and natural polymers, or the activity and efficacy of proteins and biopharmaceuticals are strongly dependent ...

Although biopharmaceutical manufacturing covers an extensive range, it is essential that each iteration of a unit operation is in compliance with an unyielding set of operational parameters and ...
