生物活性

L-Cysteine (Cysteine) is an orally active conditionally essential amino acid with hypoglycemic effects, which acts as a precursor for biologically active molecules such as hydrogen sulphide (H2S), glutathione and taurine. L-Cysteine promotes the proliferation and differentiation of neural stem cells via the CBS/H2S pathway. L-Cysteine suppresses ghrelin and reduces appetite in rodents and humans. L-Cysteine can be used as an anorectic agent[1][2][3][4].

Cell Viability Assay[2]

Cell Line: NSCs
Concentration: 0.1-50 μM
Incubation Time: 24 and 48 h
Result: Obviously improved the cell viability of NSCs in a dose-dependent manner at lower doses (0.5, 1, 5 μM) and increased the ratio of BrdU-positive cells against total NSCs at 24 h.

Cell Viability Assay[2]

Cell Line: NSCs
Concentration: 1 μM
Incubation Time: 0-90 min
Result: Induced overexpression of phosphorylated ERK (p-ERK1/2) in NSCs.

Animal Model: Male Wistar rats following an overnight 16-h fast[1]
Dosage: 1-4 mmol/kg
Administration: p.o. or i.p., a single dose for 1 h
Result: Dose-dependently decreased food intake in rats and mice and significantly increased cFLI in the area postrema in rats.

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.
