Check if the same lab product or an alternative is used in the 5 most similar protocols
ARPE-19 cells (CRL-2302™) were cultured in Dulbecco’s Modified Eagle’s Medium/F-12 medium containing 10% fetal bovine serum as previously described (Park et al., 2022 (link)). Mangiferin and H2O2 (Sigma-Aldrich, St. Louis, MO, USA) were dissolved in dimethyl sulfoxide (Thermo Fisher Scientific, Waltham, MA, USA) to prepare stock solutions, diluted to appropriate concentrations in culture medium, and then treated with cells. To trigger oxidative stress, cells were cultured in medium containing H2O2, and Mangiferin and/or zinc protoporphyrin IX (ZnPP, Sigma-Aldrich) were added 1 h before H2O2 exposure.

Mangiferin Treatment for Peri-Implantitis in Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
Upon ligature placement, mice in the mangiferin-treated peri-implantitis group were orally given mangiferin (Sigma-Aldrich Co., St Louis, MO, USA) once a day for 6 weeks (dose: 50 mg/kg bodyweight). Saline was used as vehicle, and mice in normal control and vehicle-treated peri-implantitis groups were given only saline. All animals received oral administration of mangiferin or saline from the day of ligature placement and received the last administration the day before they were sacrificed by CO2 inhalation. No mice died and all implants existed until the end of the study.

Anti-platelet Aggregation Activity of Mango

Check if the same lab product or an alternative is used in the 5 most similar protocols
The anti-platelet aggregation activity of mango and its by-products was evaluated by a turbidimetric method [14 (link)] using a lumi-aggregometer (Chrono-Log, Haverton, PA, USA). The PRP (200 × 109 platelets/L) was preincubated with 20 μL of phosphate-buffered saline, PBS, (negative control: maximum aggregation), or power extracts from each part of the mango (1 mg/mL) for 3 min at 37 °C. In order to evaluate the dose-dependent effects against platelet aggregation, different concentrations (0.1, 0.5, and 1 mg/mL) of the more active extract were tested as well as the antiplatelet properties of some standards compounds such as mangiferin (Sigma-Aldrich, St. Louis, Missouri, MO, USA) at 1 mg/mL. For all assays, platelet aggregation was induced by adding adenosine 5’-diphosphate (ADP, 4 μM) supplied by Sigma-Aldrich (St. Louis, Missouri, MO, USA) as an agonist. Platelet aggregation was measured by triplicate as the increase in light transmission occurred for 6 min and results were expressed as a percentage of inhibition of aggregation.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
