product description：

Hydroxy Dynasore (Dyngo-4a), a structural analog of Dynasore (HY-15304), is an potency improved, low cytotoxicity and non‐specific binding dynamin inhibitor with IC50 values of 0.38 μM and 2.3 μM for brain dynamin I and recombinant rat dynamin II, respectively. Hydroxy Dynasore inhibits dynamin‐dependent endocytosis of transferrin with an IC50 of 5.7 μM in vitro.

Note

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour. Refer to SDS for further information. Need more advice on solubility, usage and handling? Please visit our frequently asked questions (FAQ) page for more details.
