Combretastatin A-1 (Standard)

Combretastatin A-1 (Standard) is the analytical standard of Combretastatin A-1. This product is intended for research and analytical applications. Combretastatin A-1 is a microtubule polymerization inhibitor that binds to the colchicine-binding site of tubulin. Combretastatin A-1 inhibits the Wnt/β-catenin pathway through tubulin depolymerization mediated AKT deactivation. Combretastatin A-1 exhibits anti-tumor and anti-vascular effects.

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.
