The downstream part of a bioprocess refers to the part where the cell mass from the upstream are processed to meet purity and quality requirements. Downstream processing is usually divided into three main sections: cell disruption, a purification section and a polishing section.
Upstream extracellular signaling transduce a variety of intracellular cascades. [1] Receptors and ligands are common upstream signaling molecules that dictate the downstream elements of the signal pathway. A plethora of different factors affect which ligands bind to which receptors and the downstream cellular response that they initiate.
Downstream processing is usually considered a specialized field in biochemical engineering, which is itself a specialization within chemical engineering. Many of the key technologies were developed by chemists and biologists for laboratory-scale separation of biological and synthetic products, whilst the role of biochemical and chemical ...
Upstream and downstream can refer to: Molecular biology. Upstream and downstream (DNA), determining relative positions on DNA; Upstream and downstream (transduction) ...
This means the upstream and downstream areas of the molecule may change depending on which gene is used as the reference. The terms upstream and downstream are sometimes also applied to a polypeptide sequence, where upstream refers to a region N-terminal and downstream to residues C-terminal of a reference point.

The hospice business has undergone a dramatic transformation over the past decade, from a collection of small religious-affiliated entities into a booming mega industry dominated by companies seeking to reap big profits from the business of dying.
The relative positions of structures along strands of nucleic acid, including genes and various protein binding sites, are usually noted as being either upstream (towards the 5′-end) or downstream (towards the 3′-end). (See also upstream and downstream.) Directionality is related to, but different from, sense.
