EMEM - FAQs

Do you offer an alternative for the discontinued EMEM (Cat. No. 670086)?

Unfortunately, we do not have a direct replacement for EMEM (Cat. No. 670086). The best alternative is to use powder MEM with NEAA (Cat. No. 41500018) and then add bicarbonate to 1.5 g/L and pyruvate to 1 mM final. This will almost be an exact replacement, but relies on having to make and filter a liquid from the powder.

The next best alternative is to use liquid MEM with NEAA (Cat. No. 10370021). This would require the addition of glutamine (2 mM final) and pyruvate (1 mM final) to equal the concentrations in the discontinued product. In this version, the bicarbonate concentration would be higher (2.2 g/L) than that in the discontinued product (1.5 g/L).
