LC-U7-44

LC-U7-44 is a potent USP7 inhibitor with an IC₅₀of 0.96 μM. LC-U7-44 binds to the hydrophobic catalytic pocket of USP7, forming hydrogen bonds with Gln297, Arg408, Asp295, Val296, and Gln351, and hydrophobic interactions with Leu406. LC-U7-44 exerts anti-proliferative effects on prostate cancer cells. LC-U7-44 can be used for the research of prostate cancer.

For research use only. We do not sell to patients.

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.
