L(-)-Tyrosin, weißgraues Puder Reagenz für die Zellkultur
L(-)-Tyrosin
Storage: Store at room temperature (15-30 °C)
L-Tyrosine is one of the three aromatic amino acids, and is formed from the hydroxylation of phenylalanine.
L-Tyrosine is used in cell culture media and is a component of MEM amino acids solution. L-Tyrosine has been used in a cell culture study of the amino acid transport system b0,+ in epithelial cells isolated from chicken jejunum.
