Alpha medium (mod. MEM) liquid medium
Alpha Medium is a modified MEM medium, originally developed to grow Chinese Hamster kidney cells in vitro. Modification was done by an increase in the concentration of the amino acids, vitamins, lipoic acid, and pyruvate. Alpha medium supports the growth of bone marrow cells under both mononolayer and suspension culture conditions. The medium is also suitable for amniotic fluid cells in chromosome analysis. Another widely used supplement modification are nucleosides.
This medium is also available as a standard in powder with a minimum order of 500 litres; pack sizes are 10, or 50 litres.
