Assay conditions were selected to enable measurement of free light chains in the concentration range between 0.1 and 20 mg/l. The normal range for free lambda chains in serum was found to be 0.4-4.2 mg/l and for free kappa chains it was 1.6-15.2 mg/l.he normal range for free lambda chains in serum was found to be 0.4-4.2 mg/l and for free kappa chains it was 1.6-15.2 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.
Although the Fairchild Channel F, released in 1976, was the first true removable game system, Atari once again had the first such system to be a commercial success. Introduced in 1977 as the Atari Video Computer System (VCS), the 2600 used removable cartridges, allowing a multitude of games to be played using the same hardware.
