Data Sheet Modified Amino Acids Innovative chemicals for process intensification in cell culture media Sulfo-Cysteine Sodium Salt Emprove® EXPERT Modified amino acids are in-house manufactured amino Product Information acid derivatives with specific properties enabling the Chemical Name L-Cysteine S-sulfate Sodium Salt intensification of cell culture processes. sesquihydrate Together with the companion product Phospho-Tyrosine CAS Number 150465-29-5 disodium salt, the new modified amino acid Sulfo- Molecular weight 250,23 Cysteine sodium salt can be used as replacement for Chemical Formula C3H6NNaO5S2 ·1.5H2O cysteine to generate highly concentrated, neutral pH Physicochemical feeds. Both modified amino acids eliminate the need Information for alkaline feeds, which are normally applied to ensure pH Value 5.0 - 8.0 (10g/L, H2O, RT) solubility and stability of the unmodified amino acids tyrosine and cysteine. Solubility Up to 1.3M (H2O, RT) Utilization of just one single, neutral pH feed is a revolutionary idea to simplify fed-batch processes. It optimizes the application by reducing the number of necessary feeds and corresponding materials, while also reducing pH spikes. It also allows the development of formulations which are stable at room temperature. The use of modified amino acids can furthermore have positive impacts on cell culture duration or productivity. The high feed concentration achievable using modified amino acids allows to lower the feed volume addition in biopharmaceutical manufacturing and thus may bring an increase in titer. In addition to showing strong positive characteristics for the use in biopharmaceutical processes, there is no impact of using modified amino acids on mAb glycosylation and charge variants. On top of that, sulfo-cysteine enables a significant reduction of fragmentation and trisulfide bonds linkages in IgG and therefore a better protein quality.
