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.
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.

M-Clarity Program

As part of our EMPROVE® Program, our raw materials are offered with EMPROVE® Dossiers which provide comprehensive, up-to-date documentation to help you navigate regulatory challenges, manage risks, and improve your manufacturing processes.
