Cell culture medium ,α-MEM

α-MEM (α Minimum Essential Medium) is a modified medium from MEM. Compared with MEM , α-MEM has added sodium pyruvate, zinc sulfate, vitamin B12, biotin, ascorbic acid and other components, and is widely used for the culture of various mammalian suspension and adherent cells. α-MEM is divided into the types of nucleoside-containing and non-nucleoside-containing. The nucleoside-free and deoxynucleoside-free α-MEM is commonly used as a screening medium for DG44 and other DHFR-deficient cells.
