    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.

    Features and Benefits

    Reduced complexity in fed-batch process

    High concentrations of modified cysteine in main feeds at neutral pH

    Prevention of caustic shocks in the bioreactor due to high pH feeds

    More convenient preparation process with less contamination risks

    Reduction of recombinant protein fragmentation and decrease in trisulfide bond content

    Higher feed stability at room temperature
