Segetalin B
Based on 2 publication(s) in Google Scholar
Segetalin B, an orally active cyclopentapeptide found in Vaccaria segetalis, possesses estrogen-like activity. Segetalin B promotes mineralization of ovariectomized rat-derived bone marrow mesenchymal stem cells (BMSCs) in vitro and increases the level of osteocalcin, BMP-2, ALP, and SIRT1 activity. Segetalin B is promising for research of post-menopausal osteoporosis (PMOP).

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 40% PEG300 5% Tween-80 45% Saline
