L-Cystine (dihydrochloride)

L-Cystine dihydrochloride is the dihydrochloride salt form of L-Cystine (HY-N0394) . L-Cystine dihydrochloride elevates Nrf2 protein expression and activates Nrf2 transcription factor. L-cystine dihydrochloride reduces ROS generation and protects against oxidant- or Doxorubicin (HY-15142A) -induced apoptosis. L-Cystine dihydrochloride combined with L-theanine (HY-15121) enhances the production of antigen-specific IgG by increasing glutathione (GSH) levels and T helper 2 (Th2) mediated responses in mice. L-Cystine dihydrochloride is promising for research of cystinuria and kidney stones[1][2][3][4][5][6]
