Dynamin IN-3

Dynamin IN-3 is an inhibitor of dynamin I. Dynamin IN-3 inhibits the GTPase activity of dynamin I, with an IC₅₀of 3.3 μM (based on sheep dynamin I)—and blocks clathrin-mediated endocytosis.

In Vitro

Dynamin IN-3 (compound 97) (4.3 μM) inhibits clathrin-mediated endocytosis in U2OS cells with an IC₅₀ of 4.3 μM^[1].
Dynamin IN-3 (3-20 µM) inhibits CME in U2OS cells, with 3 and 20 µM reducing transferrin uptake and 20 µM producing near-complete loss of transferrin signal^[1].
Dynamin IN-3 (30 mM stock; 30 min) inhibits native sheep brain dynamin I GTPase with an IC₅₀ of 3.3 μM^[1].

Help & FAQs

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.
