The rapid evolution of membrane chromatography and adsorption technologies has significantly impacted protein purification processes in the biopharmaceutical and biotechnology sectors. This integrated ...

Most adsorption chromatography methods are based on a direct chemical interaction of a solid-phase ligand with a complementary target site on some population of biomolecules. Examples include ...

What is gas chromatography and liquid chromatography? Gas chromatography is a chromatographic method that uses gas as a mobile phase. The sample flows through the gas system and is gasified before ...

When the components in the mixture of solutions are moved forward in the mobile phase by the material moving the sample, these components pass through the stationary phase. The difference in size and ...

METHODS have recently been proposed (refs. 1 and 2 and Walkenstein, S., Knebel, C., MacMullen, J., and Seifter, J., private communication) for the identification and quantitative determination of 2 - ...

A Phase II manufacturing process that used a high titre antibody fragment secreting, high-cell-density E. coli expression system and Upfront’s 2nd Generation EBA chromatography resulted in a 60% ...

Thin layer chromatography is used to analyse mixtures: determine the number, identity, and purity of compounds present in a mixture. This technique can also be used to visualize the progress of a ...

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 ...
