Effective Cryopreservation of a Bioluminescent Auxotrophic -Based Amino Acid Array to Enable Long-Term Ready-to-Use Applications.

Amino acid arrays comprising bioluminescent amino acid auxotrophic are effective systems to quantitatively determine multiple amino acids. However, there is a need to develop a method for convenient long-term preservation of the array to enable its practical applications. Here, we reported a potential strategy to efficiently maintain cell viability within the portable array.
