Beraprost sodium (BPS), the sodium salt of Beraprost which is a synthetic analog of epoprostenol (a prostaglandin), is a stable, orally bioactive prostacyclin analogue with vasodilatory, antiplatelet and cytoprotective effects. It acts by binding to prostacyclin membrane receptors ultimately inhibiting the release of Ca2+ from intracellular storage sites. This reduction in the influx of Ca2+ has been postulated to cause relaxation of the smooth muscle cells and vasodilation. is a medication used in Asian countries such as Japan and South Korea, as a vasodilator and antiplatelet agent. It is classified as a prostacyclin analog. It has been studied for the treatment of pulmonary hypertension and for use in avoiding reperfusion injury.

Tube formation assay[1]
In brief, endothelial cells (1 × 104) were seeded in a 48-well plate coated with 100 μl of growth factor-reduced Matrigel TM and incubated with and without varied concentrations of BPS (Beraprost sodium) at 0.1, 1.0, and 10.0 μmol/l for tube stabilization for 24 h at 37 °C. Tube formation was quantified by measuring the total tube loops in five random microscopic fields with a computer-assisted microscope

| Cell Assay |
The HUVECs were cultured in a modified minimum essential medium supplemented with 10% fetal bovine serum and 1% mycillin at 37 °C in 5% CO2 and 95% air. HUVECs in hypoxia group were cultured for 12 h into an airtight humidified chamber flushed with a gas mixture containing 5% CO2, 95% N2, and 1% O2 at 37 °C. HUVECs in hypoxia + BPS group were cultured with BPS (Beraprost sodium) at 1.0 μmol/l. The cells were cultured according to the manufacturer’s instructions and the culture medium was changed every 2 or 3 days. HUVECs at passage 3 were used for the following experiments[1].

Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
