Downstream processing refers to the recovery and purification of biosynthetic products, particularly pharmaceuticals, from natural sources such as animal or plant tissue or fermentation broth, including the recycling of salvageable components and the proper treatment and disposal of waste. It is an essential step in the manufacture of pharmaceuticals such as antibiotics, hormones (e.g. insulin and humans growth hormone), antibodies (e.g. infliximab . Mikhail Tswett. Russian Botanist.

Department of Microbiology. Surendranath. College. Paper Chromatography. Principle. What is Descending Paper Chromatography?. Descending paper chromatography is an analytical technique in which the mobile phase moves downward through the stationary phase. In other words, in this method, the development of the paper occurs due to the movement of the solvent downwards on the paper. Therefore, the solvent reservoir should be at the top of the paper. In this process, the movement of the solvent is governed by gravity as well as capillary action.. A. . technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at . different . rates. .. Principle. It is based on the principle of the partition of the solute between two phases/solvents. Purposes of Affinity Groups (Employee Resource Groups). Affinity Groups (AG). create an open forum for staff who share common interests/concerns to meet and support one another in creatively addressing those concerns .
