L-Tryptophan (standard) is the analytical standard of L-Tryptophan. L-Tryptophan (Tryptophan) is an orally active and essential amino acid that is the precursor of serotonin, melatonin, and vitamin B3. L-Tryptophan can promote an increase in stemness and osteogenic ability of BMSCs in vitro and in vivo. L-Tryptophan inhibits cell proliferation and induced cell cycle arrest with high levels.

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.
