KGP591

KGP591 is a tubulin polymerization inhibitor (IC₅₀ 0.57 µM). KGP591 induces significant G2/M stagnation, inhibits cell migration, disrupts microtubule structure and cell morphology in MDA-MB-231 cells. KGP591 shows antitumor activity in orthotopic model of kidney cancer (RENCA).

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.
