ELR510444 is an orally active tubulin inhibitor with an IC₅₀ of 10 μM. ELR510444 binds to the colchicine-binding site on β-tubulin, inhibits tubulin assembly, depolymerizes microtubules and blocks HIF activity. ELR510444 induces cellular microtubule loss, abnormal mitotic spindle, mitotic arrest, apoptosis, morphological changes in tumor endothelial cells, and inhibits cancer cell proliferation, angiogenesis and tumor growth. ELR510444 can be used in research related to various cancers such as renal cell carcinoma.

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.
