Description

General description

Modified amino acids are inhouse manufactured amino acid derivatives with specific properties enabling the intensification of cell culture processes.

Together with the companion product Sulfo-Cysteine sodium salt, the new modified amino acid Phospho-Tyrosine disodium salt can be used as replacement for tyrosine to generate highly concentrated, neutral pH feeds. Both modified amino acids eliminate the need for alkaline feeds, which are normally applied to ensure solubility and stability of the unmodified amino acids tyrosine and cysteine.

Features and Benefits

• Reduced complexity in fed-batch process
• High concentrations of modified tyrosine in main feeds at neutral pH
• Enhanced solubility up to 70g/l in complex feed
• Prevention of caustic shocks in the bioreactor due to high pH feeds
• More convenient preparation process with less contamination risks
• Higher feed stability at room temperature
