SKLB-03220

SKLB-03220 is a selective and orally active EZH2 covalent inhibitor with an IC₅₀ of 1.72 nM for EZH2^MUT. SKLB-03220 exhibits weak activities against other tested histone methyltransferases (HMTs) and kinases. SKLB-03220 displays noteworthy potency against ovarian cancer cell lines and induces cell apoptosis. SKLB-03220 significantly inhibits tumor growth in PA-1 xenograft model. SKLB-03220 can be used for the study of ovarian cancer.

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.
