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 Phospho-L-Tyrosine disodium Salt disodium salt, the new modified amino acid S-Sulfocysteine sodium salt can be used as replacement for cysteine 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.

Our SAFC^® portfolio of high-quality products for biopharmaceutical processing withstands strict quality control procedures and is produced according to MQ-500 requirements as defined by the M-Clarity program.
