Solid | [Uses]
L-Cystine is a sulfur containing non-essential amino acid. It is used as a cell culture media component and raw material in the commercial biomanufacture of therapeutic recombinant proteins and monoclonal antibodies. L-Cystine dihydrochloride is a modified version of L-Cystine with improved solubility. | [Flammability and Explosibility]
Notclassified | [Biochem/physiol Actions]
L-Cystine is a natural proteinogenic amino acid sulfide dimer of L-cysteine. L-cystine is used as a cell culture supplement. L-cystine is also used to characterize and identify specific amino acid transport systems in cells such as system system Xc(─) . |
