In Vitro

Pantethine (10-1000 μM) inhibits cholesterol production in mouse liver slices^[1].
Pantethine (250-1000 μM; 24 h and 72 h) reduces cholesterol levels in Vero E6 cells (35% at 24 h and 80% at 72 h)^[2].
Pantethine(100-1000 μM; After pretreatment for 1 h, the virus is added and incubated together for 2 h until the end of the experiment) reduces the infection of SARS-CoV-2 to Vero E6 and Calu-3a cells in a dose-dependent manner, which has antiviral effect^[2].
Pantethine (50-100 μM; 18 h) inhibits the release of microparticles (MPs) in a dose-dependent manner in endothelial HPMECs and HUVECs. (50-100 μM; 24 h) eliminates MP-induced oxidative and nitrosation stress in endothelial cells (HPMECs and HUVECs) and fibroblasts (NIH3T3)^[5].

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

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
