Most cells can synthesise non-essential amino acids (NEAA) through glucoaminolysis, glycolysis, or the TCA cycle. When these amino acids concentration levels are low, cells need to consume more glucose and glutamine in the media and produce excess by-products, which might affect cell growth. Adding NEAA into the cell culture medium could mitigate the potential side effects caused by self-production of these non-essential amino acids.

This NEAA concentrate contains 19 amino acids, including L-ala; L-asn; L-asp; L-glu; L-gly; L-pro and L-ser.
