ISM-PR44

ISM-PR44 is an orally active PROTAC degrader targeting BTK, with a DC₅₀ of 0.05 nM in BTK-HiBiT Ramos cells. ISM-PR44 recruits CRBN E3 ligase to induce ubiquitination and proteasomal degradation of BTK. ISM-PR44 exhibits antiproliferative and cytotoxic activities in B-cell lymphoma cells. ISM-PR44 can be used for research on B-cell lymphoma.

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.
