Cell Assay
[1]

The assay used to assess cell viability in retinal cells was the MTT reduction assay. To evaluate the effect of Citicoline and Homotaurine on cell survival, the cells are subdivided into three groups and treated for 24 hours with 1?μM, 10?μM, and 100?μM of Citicoline and with 1?μM, 10?μM and 100?μM of Homotaurine. To evaluate the neuroprotective effects of Citicoline and Homotaurine, cells are treated with Citicoline 100?μM, Homotaurine 100?μM, or Citicoline+Homotaurine 100?μM, 24 hours before glutamate treatment and 30?min before high glucose (HG) treatment. MTT is added to wells at a final concentration of 0.5?mg/mL for 1 hour at 37°C. After this time, the medium is removed and reduced MTT (blue formazan product) is solubilized by adding 100?μL DMSO to each well. After agitation of plates for 15?min, the optical density of the solubilized formazan product in each well is measured using an automatic microplate reader with a 570?nm test wavelength and a 690?nm reference wavelength[1].

Animal Administration
[1]

Mice[1]
Experiments are performed on male C57Bl/6 mice (n=69) weighing 23-27 g. The study is performed in two series. In series I, the dose-dependent effect of Citicoline on the seizure threshold in mice is evaluated. The measurements are performed 1 h after Citicoline administration. Citicoline in doses of 500 and 1000 mg/kg (0.04 mL per 20 g body weight) is injected intraperitoneally. The control animals receive an equivalent volume of physiological saline under similar conditions. In series II, the duration of Citicoline effect is estimated in 3 and 6 h after single intraperitoneal injection of Citicoline.

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.
