Ucf-101
Based on 1 publication(s) in Google Scholar
Ucf-101 is a selective and competitive inhibitor of pro-apoptotic protease Omi/HtrA2, with an IC50 of 9.5 μM for His-Omi. Ucf-101 exhibits very little activity against various other serine proteases (IC50>200 μM). Ucf-101 has a natural red fluorescence at 543 nm that is used to monitor its ability to enter mammalian cells. Ucf-101 has a significant cardioprotective effect against MI/R injury and also has certain neuroprotective effect.

Select the appropriate dissolution method based on your experimental animal and administration route.
- 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
