Assay conditions were selected to enable measurement of free light chains in the concentration range between 0.1 and 20 mg/l.

The Atari 2600, or Atari VCS before 1982, is a home video game console released on September 11, 1977 by Atari, Inc. It is credited with popularizing the use of microprocessor-based hardware and ROM cartridges containing game code, a format first used with the Fairchild Channel F game console.
The Atari console was a pioneer in the world of home-based video games, at a time when video games had been primarily reserved exclusively for play in arcades. Atari gave video game lovers the opportunity to enjoy the gaming experience within their own homes, beginning in the 1970s.
