    Cell Assay
    [1]

    Cells are seeded at a density of 2-9 × 104 cells/mL into 24-well plates for cell viability, 60-mm plates for RNA and protein analysis in DMEM containing 10% FBS (DMEM/10% FBS). After 24 h, medium is removed and cells are placed in serum-free DMEM. After 48 h, different concentrations of Asiaticoside in DMEM/10% FBS are added simultaneously to cells. Control cells are grown in DMEM/10% FBS without the addition of Asiaticoside. At different time points, the fibroblasts are harvested for analysis[1].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Administration
    [3]

    Rats[3] Sprague-Dawley rats are used to establish the Alzheimer's disease (AD) model. Asiaticoside is administered orally at 5, 15 or 45 mg/kg body weight per day for 7 days. The learning and memory function of the rats are evaluated by the MWM test 7 days after surgery. The swimming pool (180 cm in diameter) is maintained at 22-24°C, and divided into four quadrants with equal size. A hidden platform is placed in the center of one quadrant. Each of the cardinal points of these four quadrants is randomLy selected as the start location. On the pre-test day, rats are allowed to swim freely for 120 sec. During the test (days 1-4), each rat is subjected to 8 trials each day. The trial begins when a rat is placed in the pool, and ended when the rat finds the platform. The escape latency is recorded. If a rat fails to find the platform within 120 sec, the trial is terminated and the escape latency is recorded as 120 sec, and the rat is guided to the platform. On day 5, the swimming path is recorded by a video recording system, and the digital images are analyzed by the water maze software. In addition, the probe test is performed, in which the platform is removed, and the rat is allowed to swim freely in the pool for 120 sec. The swimming time in the target quadrant is recorded[3].

    • 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.
