生物活性

L-SelenoMethionine, an L-isomer of Selenomethionine, is a major natural food-form of selenium. L-SelenoMethionin is a cancer chemopreventive agent that can reduce cancer incidence by dietary supplementation and induce apoptosis of cancer cells. L-SelenoMethionine also can increase expression of glutathione peroxidase[1][2][3].

体外研究
(In Vitro)

L-SelenoMethionine (1-500 μM; 24-72 h) is selectively inhibits the growth of prostate cancer cells, compared with normal cells[2].
? L-SelenoMethionine (500 μM; 48 h) induce apoptosis in prostate cancer cells[2].
? L-SelenoMethionine (500 μM; 48 h) causes an increase in arrest in the G2-M phase of the cell cycle selectively in prostate cancer cells[2].
? L-SelenoMethionine (5 μM; 24 h) mitigates gene expression associated with the cellular stress response from 10 cGy irradiation[4].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
