Vismodegib Dose-Response in Xenopus Embryos

Check if the same lab product or an alternative is used in the 5 most similar protocols
A 1 mM stock solution of Vismodegib (MedChem Express; catalog # HY-10440) was made in DMSO. Once the embryos were confirmed to be undergoing gastrulation (Koebernick et al., 2003 (link)), twenty embryos each were treated with 6.25 μM, 12.5 μM, 18.75 μM, and 21.875 μM Vismodegib. An additional group of twenty was left untreated (control animals). Each group was kept at 15 – 18 °C in 30 mm Petri dishes until they reached stage 46 (Nieuwkoop and Faber, 1956 ). The Vismodegib solution was replaced daily to ensure consistency of the chosen concentration over time. This interval is consistent with Vismodegib’s half-life, which is suggested to be 14 hours in humans and over two days of constant plasma levels (Rudin, 2012 (link)). What the exact concentration of IC50 is for Xenopus Smo proteins is unknown.

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.
