Cell Assay

Cell Viability Assay[2]
Cell line: Hep-2 cells and HUVECs
Concentration: 10 nM and 50 nM
Incubation time: 48 h
Assay: The cell viability of Hep-2 cells and HUVECs is measured by MTT assay. Hep-2 cells and HUVECs in logarithmic growth phase are plated in 96-well plates. Following 48 h of drug treatment as indicated, 200 μL MTT (5 mg/mL) is added to each well. Cells are incubated with the MTT solution at 37°C for 4 h. Then, 150 μL DMSO is added for 5 min. The optical density (OD) values are measured at 490 nm with a Versamax Microplate reader.
Note: Combined treatment effectively reduced viability in Hep-2 cells.

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

Animal Administration

In vivo studies[3]
Animal model: 4-6 weeks-old female NOD/SCID mice
Dosage: 40 mg/kg, intraperitoneal injection, every day for 2 weeks
Administration: Mice are randomized into four groups (5 mice per group). The control and treatment groups receive intraperitoneal injections of vehicle (PBS) or Acetazolamide (40 mg/kg), MS-275 (20 mg/kg) or the combination, respectively, every day for 2 weeks. Experiments are terminated when tumor sizes exceed 2 cm3 in volume or animals show signs of morbidity. Tumor diameters are measured on a daily basis until termination.
Note: Inhibited tumor growth of NB xenografts with significant anti-tumor growth potentiation effect.

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.
