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.
The game was one of the worst commercially released games ever made and is often blamed for the game industry crash of 1983. Atari currently manages about 200 classic titles such as Centipede and Asteroids. It was sold to a French company by Hasbro in 2001.
