Protein precipitation is widely used in downstream processing of biological products in order to concentrate proteins and purify them from various contaminants. For example, in the biotechnology industry protein precipitation is used to eliminate contaminants commonly contained in blood. [ 1 ]

A person who has a news obituary (and not a paid death notice) in a national quality [1] newspaper, such as The New York Times or The Times, is usually notable. An individual obituary should be evaluated for bias in the same way as any other historical source, using the methods normally used by professional historians to evaluate historical ...
Ammonium sulfate precipitation is a useful technique as an initial step in protein purification because it enables quick, bulk precipitation of cellular proteins. [4] It is also often employed during the later stages of purification to concentrate protein from dilute solution following procedures such as gel filtration .
Names are reported under the date of death, in alphabetical order. A typical entry reports information in the following sequence: Name, age, country of citizenship at birth, subsequent nationality (if applicable), what subject was noted for, cause of death (if known), and a reference.
American obituary for WWI death Traditional street obituary notes in Bulgaria. An obituary (obit for short) is an article about a recently deceased person. [1] Newspapers often publish obituaries as news articles. Although obituaries tend to focus on positive aspects of the subject's life, this is not always the case. [2]
Unwanted proteins can be removed from a protein solution mixture by salting out as long as the solubility of the protein in various concentrations of salt solution is known. After removing the precipitate by filtration or centrifugation , the desired protein can be precipitated by altering the salt concentration to the level at which the ...
Immunoprecipitation of intact protein complexes (i.e. antigen along with any proteins or ligands that are bound to it) is known as co-immunoprecipitation (Co-IP). Co-IP works by selecting an antibody that targets a known protein that is believed to be a member of a larger complex of proteins.
