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

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 ...

High performance liquid chromatography (HPLC) has become an essential technique in pharmaceutical analysis for the separation, identification, and quantification of pharmaceuticals. Due to its high ...

DIRECT azo dyes contain in most cases a number of coloured by-products which may adversely influence the shade of the dye, its stability in light and distort its biological action. In view of the ...

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 ...

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% ...

Reviewed by Dr. Catherine Shaffer, Ph.D. Chromatography (from the Greek words chroma, "color," and graphein, "to write") is a method for the separation of a mixture. In simple terms, the process ...

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 ...
