Description_x000D_ General description_x000D_ The nutrient mixture Ham′s F-12 is developed by Ham and it has higher levels of amino acids, vitamins and trace elements. Putrescine and linoleic acid are added to the formulation. Nutrient medium was originally designed for the serum-free growth of Chinese hamster ovary and lung cells. When used with whole or dialyzed serum or in combination with hormones and transferrin, it is widely used to grow mammalian and hybridoma cells._x000D_ Application_x000D_ Nutrient Mixture F-12 Ham is used for the following applications:_x000D_ • HeLa (human cervix adenocarcinoma cells) were grown in this medium (nutrient mixture F-12 Ham) supplemented with 10% heat-inactivated fetal calf serum_x000D_ • Used in cell culture for different cells during maintenance and incubation (i.e. A549 cell line was maintained as a monolayer in nutrient mixture F-12 HAM Medium along with other components)_x000D_ • Used in media for the propagation of Cowdria ruminantium_x000D_ • Used during preparation of primary mixed glial cultures_x000D_ Kaighn′s modification of Ham′s F-12 and Coon′s F-12 has increased concentrations of amino acids and pyruvate, as well as modified salts (Konigsbergs). This medium was designed to support the growth of differentiated rat and chicken cells, and primary human liver cells._x000D_ Quantity_x000D_ Formulated to contain 11.1 grams of powder per liter of medium._x000D_ Reconstitution_x000D_ Supplement with 2.5 g/L sodium bicarbonate.
