HEK 293 cells may vary. The following proteins of interest (among many others) are commonly found in untreated HEK 293 cells: HEK 293 cells Human embryonic kidney 293 cells, also often referred to as HEK 293, HEK-293, 293 cells, or less precisely as HEK cells, are a specific cell line originally derived from human embryonic kidney cells grown in tissue culture. HEK 293 cells have been widely used in cell biology research for many years, because of their reliable growth and propensity for transfection. They are also used by the biotechnology industry to produce therapeutic proteins and viruses for gene therapy. HEK 293
Many-to-many Many-to-many The many-to-many communication paradigm is one of three major Internet computing paradigms, characterized by multiple users contributing and receiving information, with the information elements often interlinked across different websites. Developments such as file sharing, blogs, Wikis, and tagging are media forms that reflect this paradigm; these contrast with both the one-to-one (characterized by e-mail, FTP, and Telnet) and one-to-many (characterized by websites) paradigms. With the evolution to the full "many-to-many" computing paradigm, people can input and receive information to and from the Internet; they will be able to connect and communicate dynamically within a flexibly formed scope; there will
